Full textAbstract:
With the development of ubiquitous computing, recommendation systems have become essential tools in assisting users in discovering services they would find interesting. This process is highly dynamic with an increasing number of services, distributed over networks, bringing the problems of cold start and sparsity for service recommendation to a new level. To alleviate these problems, this paper proposes a hybrid service recommendation prototype utilizing user and item side information, which naturally constitute a heterogeneous information network (HIN) for use in the emerging ubiquitous consumer wireless world (UCWW) wireless communication environment that offers a consumer-centric and network-independent service operation model and allows the accomplishment of a broad range of smart-city scenarios, aiming at providing consumers with the “best” service instances that match their dynamic, contextualized, and personalized requirements and expectations. A layered architecture for the proposed prototype is described. Two recommendation models defined at both global and personalized level are proposed, with model learning based on the Bayesian Personalized Ranking (BPR). A subset of the Yelp dataset is utilized to simulate UCWW data and evaluate the proposed models. Empirical studies show that the proposed recommendation models outperform several widely deployed recommendation approaches.

Full textAbstract:
In this article, proposals for the realization of an infrastructural re-think on the way authentication, authorization and accounting (AAA) services and charging and billing (C&B) services are supplied within the ubiquitous consumer wireless world (UCWW) are set out. Proposals envisage these services being owned and organized by trusted third parties (TTPs) and utilizing new globally standardized protocols and infrastructural entity interfaces. Their implementation will affect a successful realization of the UCWW’s consumer-based techno-business infrastructure, complementing or even replacing the present legacy network-centric, subscriber-based one. The approach enables a loose dynamic, or even casual, consumer-type association between consumers (mobile users) and network/teleservice providers, and it opens the door to multifaceted benefits for consumers, for new network/teleservice providers, and for other new UCWW business entities in addition to the 3P-AAA and 3P-C&B service providers at the heart of this article’s proposals.

Full textAbstract:
It is expected that Internet of Things (IoT) revolution will enable new solutions and business for consumers and entrepreneurs by connecting billions of physical world devices with varying capabilities. However, for successful realization of IoT, challenges such as heterogeneous connectivity, ubiquitous coverage, reduced network and device complexity, enhanced power savings, and enhanced resource management have to be solved. All these challenges are heavily impacted by the IoT network topology supported by massive number of connected devices. Small-world networks and scale-free networks are important complex network models with massive number of nodes and have been actively used to study the network topology of brain networks, social networks, and wireless networks. These models, also, have been applied to IoT networks to enhance synchronization, error tolerance, and more. However, due to interdisciplinary nature of the network science, with heavy emphasis on graph theory, it is not easy to study the various tools provided by complex network models. Therefore, in this paper, we attempt to introduce basic concepts of graph theory, including small-world networks and scale-free networks, and provide system models that can be easily implemented to be used as a powerful tool in solving various research problems related to IoT.

You may forget where you left your keys when you need them. In ubiquitous computing space your keys will find you and inform you where they are. Ubiquitous computing, the third generation of computing spaces, following mainframes and personal computers, is in its incipient evolution steps. In ubiquitous computing space, sensors and computing nodes are invisibly, inconspicuously, and overwhelmingly embedded in all real-world objects and are all connected to each other through omnipresent wireless networks. The goal is to make real-world objects seem intelligent and autonomous in providing users with electronic and Internet services with users not even noticing how they are provided with these services. The real world, cyberspace, modeling, and mathematics are identified as the main constituents of ubiquitous computing in this study. These four areas are investigated one-by-one and in combination to show how they create a solid foundation for ubiquitous computing. An application of ubiquitous computing in car navigation systems is used to indicate the reliability of the proposed framework.

Over the past decade, miniaturization and cost reduction in semiconductors have led to computers smaller in size than a pinhead with powerful processing abilities that are affordable enough to be disposable. Similar advances in wireless communication, sensor design and energy storage have meant that the concept of a truly pervasive ‘wireless sensor network’, used to monitor environments and objects within them, has become a reality. The need for a wireless sensor network designed specifically for human body monitoring has led to the development of wireless ‘body sensor network’ (BSN) platforms composed of tiny integrated microsensors with on-board processing and wireless data transfer capability. The ubiquitous computing abilities of BSNs offer the prospect of continuous monitoring of human health in any environment, be it home, hospital, outdoors or the workplace. This pervasive technology comes at a time when Western world health care costs have sharply risen, reflected by increasing expenditure on health care as a proportion of gross domestic product over the last 20 years. Drivers of this rise include an ageing post ‘baby boom’ population, higher incidence of chronic disease and the need for earlier diagnosis. This paper outlines the role of pervasive health care technologies in providing more efficient health care.

In the future world of ubiquitous computing, wireless devices will be everywhere. Personal area networks (PANs) will enable communications between devices both embedded in the environment and mobile on vehicles and persons. This research determines the future prospects of PANs by examining (a) criteria that will lead to success, (b) barriers to implementation, and (c) key applications. An initial set of issues in each of these areas is identified from the literature. The Delphi Method is used to determine what experts believe what are the most important success criteria, barriers, and applications. Critical success factors that will determine the future of personal area networks include reliability of connections, interoperability, and usability. Important barriers that may inhibit the deployment of PAN are security, interference and coexistence, and regulation and standards. Key applications for PAN success include monitoring, healthcare, and smart things.

Wireless local area networks or WLANs are the necessary underlying communication technology of consumer electronics, mobile computers and mobile phones of our days. Thanks to the comfortable operations and ubiquitous applicability for work and entertainment, the demand surged for these devices in the last 15 years. WLAN solutions provide the opportunity for mobility. But these networks communicate via radio waves with devices, which can be eavesdropped on and attacked. One form of attack is jamming. This article analyses the most frequent WLAN standards and the jamming options, particularly the execution of electronic jamming in the physical layer.

Full textAbstract:
All interactions of objects, humans, and machines with the physical world are via contact forces. For instance, objects placed on a table exert their gravitational forces, and the contact interactions via our hands/feet are guided by the sense of contact force felt by our skin. Thus, the ability to sense the contact forces can allow us to measure all these ubiquitous interactions, enabling a myriad of applications. Furthermore, force sensors are a critical requirement for safer surgeries, which require measuring complex contact forces experienced as a surgical instrument interacts with the surrounding tissues during the surgical procedure. However, with currently available discrete point-force sensors, which require a battery to sense the forces and communicate the readings wirelessly, these ubiquitous sensing and surgical sensing applications are not practical. This motivates the development of new force sensors that can sense, and communicate wirelessly without consuming significant power to enable a battery-free design. In this magazine article, we present WiForce, a low-power wireless force sensor utilizing a joint sensing-communication paradigm. That is, instead of having separate sensing and communication blocks, WiForce directly transduces the force measurements onto variations in wireless signals reflecting WiForce from the sensor. This novel trans-duction mechanism also allows WiForce to generalize easily to a length continuum, where we can detect as well as localize forces acting on the continuum. We fabricate and test our sensor prototype in different scenarios, including testing beneath a tissue phantom, and obtain sub-N sensing and sub-mm localizing accuracies (0.34 N and 0.6 mm, respectively).

The ever-growing cloud computing and services provide dynamic intelligence and play an increasingly critical role in all aspects of our lives. By taking advantage of virtualized resources, cloud computing services presents an attractive means to address the challenges while realizing the potential of Mobile and Wireless Computing (MWC). The MWC paradigm can be generalized to include mobile devices, which not only incorporate sophisticated methods for users to interact with the online world through numerous applications in their devices, but are endowed with multiple sensors that enable them to contribute data as nodes in the IoT. In this context, mobile cloud services that enable widespread data collection through mobile devices and collaborative use of mobile devices to enhance existing and realize new applications are very much of interest. As such, the MWC has come to the picture seeking solutions for computing and IT infrastructures to be energy efficient and environmentally friendly.

As intelligent ubiquitous devices become more popular, security threats targeting them are increasing; security is seen as one of the major challenges of the ubiquitous computing. Now a days, applying ubiquitous computing in number of fields for human safety and convenience was immensely increased in recent years. The popularity of the technology is rising day by day, and hence the security is becoming the main focused point with the advent and rising popularity of the applications. In particular, the number of wireless networks based on ubiquitous devices has increased rapidly; these devices support transmission for many types of data traffic. The convenient portability of ubiquitous devices makes them vulnerable to security threats, such as loss, theft, data modification, and wiretapping. Developers and users should seriously consider employing data encryption to protect data from such vulnerabilities. In this paper, we propose a Rhythm Key based Encryption scheme for ubiquitous devices (Ubi-RKE). The concept of Rhythm Key based Encryption has been applied to numerous real world applications in different domains. It provides key memorability and secure encryption through user touching rhythm on ubiquitous devices. Our proposed scheme is more efficient for users than existing schemes, by providing a strong cipher.

Due to globalization, global trade is strongly growing nowadays. The use of containers has significantly increased and bringing the change on the shape of the world economy. Thus, monitoring every single container is a big challenge for port industries. Furthermore, rapid development in embedded computing systems has led to the emergence of Wireless Sensor Network (WSN) technology which enabled us to envision the intelligent containers. This represents the next evolutionary development in logistics industry to increase the efficiency, productivity, security of containerized cargo shipping. In this paper, we present a comprehensive containerized cargo monitoring system based on WSNs. We incorporated tilt/motion sensor to improve the network convergence time of container networks. Moreover, we periodically switch the nodes into sleeping mode to save energy and extend the lifetime of the network. Based on the technical implementation on a real container vessel, we strongly believed that our design which employed WSN technology is viable to be implemented in container logistics to improve port services and provide safe transport of containerized cargo.

Ubiquitous computing is an advanced technology in the age of wireless networks that supports infiltration, activation and interconnectability of all the electronic and sensor-based objects related to everyday issues, and in this manner endeavours to empower a ubiquitous stream of information and data by coordinating learning and training. Ubiquitous computing is the method of enhancing computer-based computations by making use of many computers available throughout the physical environment, but making them effectively invisible to the user. The advanced technology of science and networks is instinctively welcoming the introduction of this revolutionary computing concept that guarantees to profoundly affect the way the authors associate with computing machineries, electronic gadgets, mobile devices, cyber spaces, and related peripherals. This new emerging technology of ubiquitous computing imagines a world where inserted processors, PCs, sensors, and advanced correspondences are reasonable products that are accessible at any time. Ubiquitous computing will encompass clients with an agreeable and helpful data condition that unites physical and computational foundations into incorporated natural surroundings. This living space will include an expansion of hundreds or thousands of computing gadgets and sensors that will give new usefulness, offer specific administrations, and lift efficiency and cooperation. The current research article projects technical and operational utility of ubiquitous devices with challenging issues in emerging ubiquitous computing.

The rapid progress of wireless communication, sensing, and mobile technologies has enabled students to learn in an environment that combines learning resources from both the real world and the digital world. It can be viewed as a new learning style which has been called context-aware ubiquitous learning. Most context-aware ubiquitous learning systems employ expensive sensing technologies, such as Radio Frequency Identification (RFID), to detect the real-world learning behaviors of students and to provide personalized learning guidance accordingly. In this paper, the authors use QR (Quick Response) code, a low cost technology that is available on smart phones for detecting students' real-world learning status. Moreover, Web 2.0 technology is employed to enable students to collaboratively build a learning materials database. An experiment was conducted to investigate the relationships between the system quality, personal factors, learning motivation, perceived usefulness, and perceived ease of use, learning attitude, and behavioral intention of the students. In addition, from the interviews, it was found that most of the students felt interested in learning with the system and considered it as a helpful learning tool.

Wireless networks have a unique capability of maintaining same contact even if one moves from one location to another. It provides the flexibility and versatility for wireless communications. The wireless and mobile communications have found usefulness in the area of commerce, education, defense, home-based and industrial applications, and military environment. Wireless networks have had a significant impact on the world through the use of wireless networks; information could be sent overseas or behind the enemy lines easily, efficiently and more reliably. Wireless networking is an essential productivity tool for today's mobile workforce. With wireless networking, we can stay connected to companies and others information resources virtually anytime, anywhere. Wireless networks are becoming more and more ubiquitous in recent years, ranging from mobile analog and digital cellular telephony up to satellite broadcasting. Therefore, supporting a high Quality of Service (QoS) in delivering voice, video and data in this context has emerged as one of the most important challenge of the new century. In this research article we present a survey on introduction to wireless networks, classification of wireless networks, quality of service(QOS) parameters like bandwidth, Delay, Delay Variation (Jitter), Throughput, Energy, and finally to provide the Security to information about different parameters for end-to-end communication over wireless networks.

Full textAbstract:
For all its typically Progressive Era characteristics and national scope, the “honest weight movement” has long been hidden in plain sight. Seemingly ubiquitous and mundane, the common grocery scale was the intersecting borderland of industry, government, marketplace, and consumer. On the one hand, the regulation of weights and measures, being one of the first forms of governmental regulation of the marketplace dating back to the ancient world, seems so unobjectionable and commonplace that the Progressive Era movement for its more rigorous and efficient administration does not seem like it could have been a very controversial proposal. Who, after all, could object to clear and consistent standards of measurement and their universal application? Thus, the appearance of a movement to reform the ubiquitous and the mundane has not elicited the same historical attention that novel forms of government regulation have.

Mobile wireless communication heavily relies on the radio frequency to convey message and data. However, its limited spectrum can hardly meet the demands for the future high data rate applications. Optical wireless communication, in particular visible light communication, opens up vast optical spectrum for communication, and meanwhile can retrofit the light sources as the communication transmitters in the existing working or living environments. In conjunction with the ubiquitous cameras in hand-held consumer electronics such as smartphones and pads, optical camera communication (OCC) further takes advantages of image sensors as the communication receivers and realizes low-cost communication systems. This article first provides an overview of OCC systems. It then addresses some practical constraints, ranging from sensor low frame rate and instability, rolling shutter readout, to visual qualities of displayed images and videos, and link blockage between the transmitter and receiver. Accordingly, it introduces existing and new solutions to deal with those constraints by data modulation, newly developed camera structures, post-processing of sensed signals and non-line of sight OCC as a new form. In particular, indirect paths by either the indoor surface reflection or the outdoor atmospheric scattering are explored for link connectivity under blockage. Finally, some future research directions are suggested. This article is part of the theme issue ‘Optical wireless communication’.

The commercial success of cellular phone systems during the late 1980s and early 1990 years heralded the wireless revolution that became apparent at the turn of the 21st century and has led the modern society to a highly interconnected world where ubiquitous connectivity and mobility are enabled by powerful wireless terminals. Software defined radio (SDR) technology has played a major role in accelerating the pace at which wireless capabilities have advanced, in particular over the past 15 years, and SDRs are now at the core of modern wireless communication systems. In this paper we give an overview of SDRs that includes a discussion of drivers and technologies that have contributed to their continuous advancement, and presents the theory needed to understand the architecture and operation of current SDRs. We also review the choices for SDR platforms and the programming options that are currently available for SDR research, development, and teaching, and present case studies illustrating SDR use. Our hope is that the paper will be useful as a reference to wireless researchers and developers working in the industry or in academic settings on further advancing and refining the capabilities of wireless systems.

In a revised definition of the Davis-Goldberg concept of agribusiness, Sonka and Hudson suggest that the food and agribusiness sector might be thought of as a sequence of interrelated subsectors made up of: (1) genetics and seedstock firms, (2) input suppliers, (3) agricultural producers, (4) merchandisers or first handlers, (5) processors, (6) retailers, and (7) consumers. In applying this ubiquitous definition to global data, Goldberg (1991a) estimates that the food and agribusiness system is the largest economic sector in the world economy representing 50 percent of the global labor force, 50 percent of global assets, and 50 percent of global consumer expenditures.

conceptualisation of a world wherein human's interaction with computer technology would no longer be limited to conventional input and output devices, has now been translated into a reality with human's constant interaction with multiple interconnected computers and sensors embedded in rooms, furniture, clothes, tools, and other items that surround them. Moreover, young people's inclinations towards wireless and mobile technologies has lead researchers to propose that the use of mobile/internet learning helps in reducing both time and location constraints within the educational environment. Thus, the present study attempts to explore the critical factors that help students in adopting ubiquitous internet (u-internet) in India. A questionnaire in English was developed and data were collected from 134 students in different majors at a large Indian central university using convenience sampling technique. In order to test the reliability of the developed instrument and extract factors related to it, statistical techniques such as Cronbach's Alpha reliability test, exploratory factor analysis, symmetric measures and correlation analysis were carried out. Preliminary analysis indicates that in terms of internal consistency/reliability, the developed scale in India performed satisfactorily. The EFA findings shows that 12-item scale can be categorized into 4 different factors. Thus, the four factors were named as “efficiency”; “information”; “performance” & “techno”. Standard loadings on each item was more than 0.550. Further, high and strong level of correlation was observed between the derived factors.

Full textAbstract:
The recent advances of ubiquitous wireless infrastructures and requirements for high speed context-aware computing have created the opportunities to supply the high efficient location based service (LBS) in indoor wireless local area network (WLAN) environment. Because of the serious multi-path effect, unpredictable co-channel interference and inherent equipment noise, the measured signal strengths vary a lot in the real-world indoor environment. And this strength variation will also result in the performance deterioration of radio map-based neighboring matching algorithm. In response to this compelling problem, we propose the adoption of adaptive autocorrelation-based signal preprocessing method as a specific solution by effectively eliminating the singular strength from the original fingerprint set. Finally, the feasibility and effectiveness of autocorrelation-based preprocessing are also verified by decreasing about 33.4% and 32.9% of errors in k nearest neighbor (KNN) and weighted KNN (WKNN).

In the twenty-first century, the impact of wireless and ubiquitous technologies is changing the way people perceive and interact with the physical world. These communication paradigms promise to change and redefine, in a reasonably short period of time, the most common way of our everyday living. The continuous advances in the field of Wireless Sensor Networks and their direct application in Smart Spaces are clear examples of it. However, in order for this kind of new generation infrastructures to have a large-scale dissemination, there are still some open issues to tackle. In this way, this paper presents nSOM, a service-oriented framework based on sensor network design that provides internetworking services with the Internet cloud. This lightweight middleware architecture implements an agent-based virtual sensor service approach which is a compact semantic knowledge management scheme based on a dynamic composition model.

Computer-facilitated self-service technologies (SSTs) have become ubiquitous in today’s consumer-focused world. Yet, few human–computer interactions elicit such dramatically polarizing emotional reactions from users as those involving SSTs. ATMs, pay-at-the-pump gas stations, and self-scanning retail registers tend to produce both passionate supporters and critics. While negative comments often center on unpleasant personal user experiences, the actual “abuse” related to such systems is really much deeper and more complex. SSTs carry with them a number of potentially insidious consequences, including the exploitation of consumers as uncompensated temporary workers; the sacrifice of our inherent humanity to delegate both skills and cognition to electronic helpers; and the enabling of a new type of posthuman consumer identity, where each transaction is completed by a cyborg entity constructed of the human on one side and the electronic mechanism on the other. As a result, we may ultimately lose the boundary between the human and the machine.

With more and more video application scenarios and increasing complexity, the popularization of multimedia information and the urgent need to update wireless sensor networks have led to the emergence and development of wireless multimedia sensor networks. This paper focuses on the rate control optimization algorithm of multimedia-based ubiquitous power sensor network, which is mainly studied from three aspects: constructing algorithm verification platform based on multimedia technology, performance analysis, and optimization of rate control optimization algorithm based on multimedia technology. An algorithm verification platform is established based on multimedia technology. This article uses a scalable video coding method to design a client-driven scalable video transmission system. The simulation results show that the algorithm can effectively improve the video quality. The algorithm of rate control based on multimedia technology is proposed. A reliable multipath routing algorithm based on AODV is proposed. Based on the energy balance algorithm, the node-independent routing mechanism and link quality estimation model are introduced. An independent and reliable active/standby communication link to the node of the destination node is established. Linux, the full name of GNU/Linux, is a free-to-use and freely disseminated Unix-like operating system. It is a POSIX-based multiuser, multitasking, multithreaded, and multi-CPU operating system. With the development of the Internet, Linux has gained support from software enthusiasts, organizations, and companies all over the world. In addition to maintaining a strong momentum of development in servers, it has made considerable progress in personal computers and embedded systems. Under the Linux platform, a large number of tests are performed and the performance of the control code rate is analyzed. The so-called sensor network is a distributed intelligent network system that is composed of a large number of small sensor nodes with wireless communication and computing capabilities deployed in the active area through a self-organizing method that can autonomously complete designated tasks according to the environment. The distance between the nodes of the sensor network is very short, and the multihop wireless communication method is generally used for communication. The sensor network can run in an independent environment, or it can be connected to the Internet through a gateway so that users can access it remotely. It is concluded that ABR is the most suitable rate control algorithm for video transmission. According to the CQP experiment results, the QP value set in the improved ABR algorithm is at most 40; the security from the construction of the ubiquitous power sensor network to the final monitoring data collection and upload process is verified by simulating the hypothesis attacks and faults. It is proved that the construction of ubiquitous power sensor network can reduce the energy consumption and delay of monitoring data collection and verify the superiority of constructing ubiquitous power sensor network.

Full textAbstract:
Energy is an important consideration in the design and deployment of wireless sensor networks (WSNs) since sensor nodes are typically powered by batteries with limited capacity. Since the communication unit on a wireless sensor node is the major power consumer, data compression is one of possible techniques that can help reduce the amount of data exchanged between wireless sensor nodes resulting in power saving. However, wireless sensor networks possess significant limitations in communication, processing, storage, bandwidth, and power. Thus, any data compression scheme proposed for WSNs must be lightweight. In this paper, we present an adaptive lossless data compression (ALDC) algorithm for wireless sensor networks. Our proposed ALDC scheme performs compression losslessly using multiple code options. Adaptive compression schemes allow compression to dynamically adjust to a changing source. The data sequence to be compressed is partitioned into blocks, and the optimal compression scheme is applied for each block. Using various real-world sensor datasets we demonstrate the merits of our proposed compression algorithm in comparison with other recently proposed lossless compression algorithms for WSNs.

Ambient media is a new form of media, which deals with media objects that mediate information throughout the natural environment of people. In ambient media environments, the media becomes part of daily life activities and environments – similar to location based services, where the physical world has a virtual digital overlay providing digital services for the consumer on a specific location. As any new media environment, also ambient media environments enable a new form and way of communication and impact on human culture. This article should provide a first starting point for discussing the wide topic of ambient media, and introduce aspects that relate to the development of an ambient media culture. The article shows different notions and discussions from a media cultural perspective, that impacts on ambient media environments. It compiles the results of the discussions that took place during the 2nd meeting of the Nordic network “The Culture of Ubiquitous Information” in Helsinki on the 19th January 2011. It shall lead to an initial discussion of this aspect and provide new ways of thinking how ubiquitous computation will impact human culture and which impact theories of Martin Heidegger or Katherine Hayles have in this context.

There has been a significant shift in the purchase of media by brands in the last decade. Brands have moved from spending money on the ever-present television and print media to the ubiquitous digital media of today. Consumers, however, are wary of marketing communications from companies and prefer reviews and opinions from friends or other consumers. In the new hyperconnected world, they are online reviews (i.e., electronic word-of-mouth or eWOM). Consequently, it has become imperative for marketers to measure and manage eWOM, and several companies today rely on social media command centres (SMCCs) for this. Companies use SMCCs to unearth fans and reveal influencers. The prevalent thinking is that by actively interacting with these influencers, eWOM can be positively impacted, which, in turn, may enhance the engagement of prospective customers with the brand. The present study proposes a model for the relationship between eWOM and consumer engagement (CE). Additionally, it details a comprehensive classification framework of CE and reveals both the experts’ and consumers’ perspectives in this field by adopting a grounded theory–content analysis approach. The findings suggest that eWOM leads to CE.

Software-defined network is an encouraging research area that realizes updates throughout an entire network, and a wireless network is ubiquitous in an up-to-date world. The combination of these techniques, which is referred to as a wireless software-defined network, has been a significant development in numerous testbeds. The extensive use of distributed controllers that achieved elastic extension and are fault tolerant in large-scale wireless networks is hopeful. Despite their profits, they generate significant overhead in synchronizing network information. Thus, power-hungry wireless software-defined network devices limit the usage of distributed controllers in wireless networks. The patterns of storing network information have a crucial effect on controller performances, as they determine the probability of processing requests based on local data. To address this problem, we identify a better pattern for controllers to retain proper network information to balance costs in terms of both synchronous traffic and response time. We analyze the characteristics of distributed controllers and propose an overhead model of a distributed controller in a wireless software-defined network. Based on this model, we design an asymmetric network information cache to make trade-offs among different controller architectures. The asymmetric network information cache measures real-time network traffic and computes the traffic among sub-networks controlled by controller nodes. Then, the controller asymmetrically caches suitable network data to substantially busier nodes. The experimental results indicate that the asymmetric network information cache achieves a trade-off between synchronous traffic and the average response time.

Wireless Sensor Networks (WSNs) are a resource-constrained network class recognized as a major energy consumer. Wireless sensor technologies are used in many commercialized industrial automation processes and other real-world applications. The WSN protocol is well-suited to harsh situations where deployment is difficult or impossible, such as the battlefield, a toxic chemical plant, the cloud, fog computing, and the Internet of Things, but not in a high-temperature network infrastructure environment. WSNs have introduced various Energy-Efficient Routing Protocols based on network (NW) organization and protocols in recent years. Various WSN routing options for energy efficiency are explored in this work. The WSN Energy Efficient Routing Protocol is compared to other routing systems. We also compare and investigate better WSN routing algorithms for cloud computing, fog computing, and the Internet of Things.

Full textAbstract:
Over the past decade, there has been exponential growth in the per capita rate of medical patients around the world, and this is significantly straining the resources of healthcare institutes. Therefore, the reliance on smart commercial off-the-shelf (COTS) implantable wireless medical devices (IWMDs) is increasing among healthcare institutions to provide routine medical services, such as monitoring patients’ physiological signals and the remote delivery of therapeutic drugs. These smart COTS IWMDs reduce the necessity of recurring visits of patients to healthcare institutions and also mitigate physical contact, which can minimize the possibility of any potential spread of contagious diseases. Furthermore, the devices provide patients with the benefit of recuperating in familiar surroundings. As such, low-cost, ubiquitous COTS IWMDs have engendered the proliferation of telemedicine in healthcare to provide routine medical services. In this paper, a review work on COTS IWMDs is presented at a macro level to discuss the history of IWMDs, different networked COTS IWMDs, health and safety regulations of COTS IWMDs and the importance of organized procurement. Furthermore, we discuss the basic building blocks of IWMDs and how COTS components can contribute to build these blocks over widely researched custom-built application-specific integrated circuits.

Internet of Things (IoT) is a novel approach of connecting things/objects and thus transmitting information between various entities of the physical world or to the control centers where this information can be interpreted. IoT has been poised as the next evolution of internet promising to change our lives by involving a seamless access to people and devices in a ubiquitous way leading to a smart world. These devices, often referred to as smart items or intelligent things can be home appliances, healthcare devices, vehicles, buildings, factories and almost anything networked and fitted with sensors, actuators, and/or embedded computers. IoT promises to make the world smarter and proactive by enabling things to talk and others to understand. This work first presents an insight into the origin of IoT and its network as well as data centric architecture while listing the major possibilities. The seemingly important role and challenges of using Wireless Sensor Networks (WSN) which acts as the base in sensing and monitoring has been discussed. Since, the future lies in utility computing, best realized in the form of cloud computing, a cloud centric view of IoT is also presented.

Full textAbstract:
AbstractThis article opens up a new perspective on market liberalism's triumph in the late twentieth century through an examination of the political battles that were fought in Britain over the regulation of homework. Ubiquitous in the late Victorian era, this form of waged labor was curtailed by Edwardian wage regulations but resurged in the 1970s as a result of competition from low-wage economies abroad and fast-changing consumer tastes. Alongside growing use of homeworkers in consumer industries, new information technologies made it increasingly possible for some forms of professional work to move into the home. This article explores the debates that swirled around these different forms of homework, pitting antipoverty campaigners, feminists, and activists against ministers, employers, and civil servants. It shows how Conservative and New Labour governments failed to recognize the structural similarities between Victorian-style “sweated” labor and the emerging world of telework, freelancing, and self-employment, and how the intellectual excitement generated by Britain's transition toward a postindustrial future dovetailed with the New Right commitment to deregulation and the creation of “flexible” labor markets. A brief comparison with homework in the United States underlines the value of local, particular histories to our larger understanding of ideological change in modern societies.

Path tracking in wireless and mobile environments is a fundamental technology for ubiquitous location-based services (LBSs). In particular, it is very challenging to develop highly accurate and cost-efficient tracking systems applied to the anonymous areas where the floor plans are not available for security and privacy reasons. This paper proposes a novel path tracking approach for large Wi-Fi areas based on the time-stamped unlabeled mobility map which is constructed from Smith-Waterman received signal strength (RSS) measurement matching. Instead of conventional location fingerprinting, we construct mobility map with the technique of dimension reduction from the raw measurement space into a low-dimensional embedded manifold. The feasibility of our proposed approach is verified by the real-world experiments in the HKUST campus Wi-Fi networks, sMobileNet. The experimental results prove that our approach is adaptive and capable of achieving an adequate precision level in path tracking.

Lithium-ion batteries have become ubiquitous in a variety of energy storage applications ranging from grid storage to consumer electronics to electric vehicles. However, their continued usage in a vastly dynamic world predicates on their ability to be not only safe, sustainable, and reliable, but also contain high capacity under a variety of fast charge/discharge conditions. Multiple studies have shown that increased performance at fast charge/discharge rates can be achieved through systematic manipulation of key interfaces at various nano-, micro- and mesoscales of the electrode. Through careful tuning of the processing and chemical modification of polymeric binders, capping agents, and conductive additives, rational design of battery electrodes with specific performance characteristics can be achieved. Careful manipulation of interfacial chemistries can help push the boundaries of electrochemical performance in a wide variety of cell components. This presentation will focus on the chemical manipulation of polymers within a composite electrode to gain fundamental insights needed for the realization of next-generation battery systems.

Concept of Industry 4.0 and implementation of Cyber Physical Systems (CPS) and Internet of Things (IoT) in industrial plants are changing the way we manufacture. Introduction of industrial IoT leads to ubiquitous communication (usually wireless) between devices in industrial control systems, thus introducing numerous security concerns and opening up wide space for potential malicious threats and attacks. As a consequence of various cyber-attacks, fatal failures can occur on system parts or the system as a whole. Therefore, security mechanisms must be developed to provide sufficient resilience to cyber-attacks and keep the system safe and protected. In this paper we present a method for detection of attacks on sensor signals, based on e insensitive support vector regression (e-SVR). The method is implemented on publicly available data obtained from Secure Water Treatment (SWaT) testbed as well as on a real-world continuous time controlled electro-pneumatic positioning system. In both cases, the method successfully detected all considered attacks (without false positives).

Full textAbstract:
Rice is a very popular food throughout the world and the basis of the diet of the citizens of many countries. It is used as a raw material for the preparation of many complex dishes in which different ingredients are involved. Rice, as a consequence of their cultivation, harvesting, and handling, is often contaminated with spores of Bacillus cereus, a ubiquitous microorganism found mainly in the soil. B. cereus can multiply under temperature conditions as low as 4 °C in foods that contain rice and have been cooked or subjected to treatments that do not produce commercial sterility. B. cereus produces diarrhoeal or emetic foodborne toxin when the consumer eats food in which a sufficient number of cells have grown. These circumstances mean that every year many outbreaks of intoxication or intestinal problems related to this microorganism are reported. This work is a review from the perspective of risk assessment of the risk posed by B. cereus to the health of consumers and of some control measures that can be used to mitigate such a risk.
