Streszczenie:

One of the most important types that used to transfer data between nodes without using wires is a “wireless communication network”, where the transmission of data is censored remotely by using electromagnetic waves such as radio waves that usually implemented in the physical layer of the network. Continuous improvements in wireless network technology have reduced the security and speed differences between types of networks (wired and wireless), but in turn, increased security threats to wirelessly transmitted data. Wireless networks are weak in terms of "privacy protection" because anyone who is within the coverage area of a wireless network can attempt to break into that network. Hacking incidents have been reported frequently in places with shared free networks, and it has been observed that the places of open distributed networks of the Internet are most at risk of complete penetration of your phone or PC data. To solve this problem, several programs have been developed that provide protection for wireless networks that differ in terms of security. Some of them did not provide sufficient protection for wireless networks, such as Wired Equivalent Privacy (WEP), and others made progress in preventing intrusions compared to their predecessors, such as Wi-Fi Protected Access (WPA).

VoIP is a technology used to communicate voice remotely and directly using data communication lines with TCP / IP protocol. But basically, VoIP communication does not guarantee data security when doing communication. A very important security system is added in VoIP communications to maintain the confidentiality of communication, so that communication can not be recorded and played back. To build a security when communicating VoIP, then in this study added an SRTP-TLS security system. The study was conducted on wireless networks by comparing the security of data communications when using the SRTP-TLS security system and without using a security system.Keywords: Wireless, Security System, VoIP

Li-Fi stands for Light-fidelity. The technology was very new and proposed by the German Physicist Harald Hass in 2011. Li-Fi basically aims to replace Wi-Fi by using light to transmit internet signals. It works on the principle of visible light communication I.e .use of visible light for communication. Though Li-Fi is a system that is capable of transmitting data at high speeds over the visible light, ultraviolet and infrared spectrum but in its present state only LED lambs can be used. It consists of a light bulb which is used as an emitter and a photo diode as a receiver. Li-Fi provides transmission of data through an LED light bulb that varies in intensity faster than human eye can follow .It is ideal for high density wireless data coverage in confined area where there is no obstacle. It provides better bandwidth efficiency, availability& security than wifi. The technology is actively being developed by several organizations across the globe. In this project we tried to show a basic prototype of wireless data transmission using LiFi and what future it holds within itself for the new generation needs

Streszczenie:

In this article, we propose a novel wireless powered communication network, which is composed of two multiple antennas hybrid access points and a series of distributed wireless devices. The two hybrid access points transmit downlink wireless energy to the wireless devices and receive uplink wireless messages from the wireless devices; meanwhile, the information of wireless devices nearer to their corresponding hybrid access point should be transmitted to the faraway hybrid access point. To improve the throughput performance of some wireless devices away from their corresponding hybrid access point, we propose a clustering-collaboration interactive communication protocol with multiple antennas by Time Division Multiple Access, where two of the distributed wireless devices are selected as cluster heads to help relay information of other cluster members, which can efficiently improve some faraway wireless devices’ throughput performance. However, its performance is also constrained by cluster heads’ high-energy consumption. To solve this energy imbalance problem, multi-antenna energy beamforming technology is exploited for the hybrid access points, which distributes more transmission power to the cluster heads to balance all the wireless devices’ energy consumption. In particular, we obtain the proposed system’s throughput performance through the multi-antenna cluster-based collaboration, and verify through simulations that this scheme can effectively enhance user unfairness and improve the throughput performance.

The contemporary wireless transmitter in addition to information symbols transmits also training symbols in order to help the receivers in the estimation of the information symbols by estimating the channel state information (CSI). In this paper, we look at existing wireless communication technologies in light of environment-aware wireless communications, which is a new concept of wireless communications that queries the time-invariant CSI from the local or global database, using information about the transmitter and receiver location. Thus, this study is the first critical review of the potential of today’s terrestrial wireless communication systems including wireless cellular technologies (GSM, UMTS, LTE, NR), wireless local area networks (WLANs), and wireless sensor networks (WSNs), for estimating CSI, the ratio between training and information symbols and the rate of channel variation, and the potential use of time invariable CSI in environment aware wireless communications. The research reveals, that early communication systems provide means for narrowband channel estimation and the CSI is only available as channel attenuation based on signal level measurements. By increasing the frequency bandwidth of communications, the CSI is estimated in some form of channel impulse response (CIR) in almost all currently used radio technologies, but this information is generally not available outside the communication systems. Also, the CSI is estimated only for the channel with active communications. The new radio technology (NR) offers the possibility of estimating the CIR for non-active channels as well, and thus the possibility of initiating environmentally aware wireless communications.

The Wireless communication has been booming in the recent years. However, not much has been done to accomplish communication in water in a wireless manner which can be useful in many scenarios. Most of the communication modes that are existing as of now are either not reliable or are very expensive. IR rays can pass through water and thus be used in case of line of sight for communication purpose in this medium. This IR communication using Keyboard uses two units both controlled by ATmega family microcontroller. Both of the units have IR trans-receivers as communicating agents. Keyboards are needed to be connected on both the ends to enter input to the system. The communication messages get displayed on the LCD connected to the system. The system communicates with confirmation key that is sent back by receiving unit to the sending unit. In this way wireless communication is implemented with great efficiency within a line of sight range of about 3-4 meters under the water with the help of IR wireless underwater Communication project.

<p class="Abstract">For military divers, having a robust, secure, and undetectable wireless communication system available is a fundamental element. Wireless intercoms using acoustic waves are currently used. These systems, even if reliable, have the defect of being easily identifiable and detectable. Visible light can pass through sea water. Therefore, light can be used to develop short-range wireless communication systems. To realize secure close-range underwater wireless communication, the Underwater Optical Wireless Communication (UOWC) can be a valid alternative to acoustic wireless communication. UOWC is not a new idea, but the problem of the presence of sunlight and the possibility of using near-ultraviolet radiation (near-UV) has not been adequately addressed in the literature yet. In military applications, the possibility of using invisible optical radiation can be of great interest. In this paper, a feasibility study is carried out to demonstrate that UOWC can be performed using near-ultraviolet radiation. The proposed system can be useful for wireless voice communications between military divers as well as amateur divers.</p>

Autonomous vehicles (AVs) are the future of mobility. Safe and reliable AVs are required for widespread adoption by a community which is only possible if these AVs can communicate with each other & with other entities in a highly efficient way. AVs require ultra-reliable communications for safety-critical applications to ensure safe driving. Existing vehicular communication standards, i.e., IEEE 802.11p (DSRC), ITS-G5, & LTE, etc., do not meet the requirements of high throughput, ultra-high reliability, and ultra-low latency along with other issues. To address these challenges, IEEE 802.11bd & 5G NR-V2X standards provide more efficient and reliable communication, however, these standards are in the developing stage. Existing literature generally discusses the features of these standards only and does not discuss the drawbacks. Similarly, existing literature does not discuss the comparison between these standards or discusses a comparison between any two standards only. However, this work comprehensively describes different issues/challenges faced by these standards. This work also comprehensively provides a comparison among these standards along with their salient features. The work also describes spectrum management issues comprehensively, i.e., interoperability issues, co-existence with Wi-Fi, etc. The work also describes different other issues comprehensively along with recommendations. The work describes that 802.11bd and 5G NR are the two potential future standards for efficient vehicle communications; however, these standards must be able to provide backward compatibility, interoperability, and co-existence with current and previous standards.

In anticipation for an automated future, the Internet of Things (IoT) has rapidly connected more gadgets. Thus, IoT applications' performance requirements present new challenges. Power consumption, service quality, localization, security, and exact wireless channel propagation modelling and characterization are potential issues. When connecting separate sensors wirelessly, the latter is crucial. Channel modelling varies by location because environmental factors affect wireless signal range and quality. Wireless communication technologies are widely used for disaster victim and responder tracking and machine health monitoring in networked manufacturing. Data communication in such systems must be real-time or risk financial losses or human lives. Facilitating real-time medium access via license-free bands in uncontrolled situations is difficult because all communicating stations must be synchronized. (real and nonreal-time). In open communication, medium access protocols cannot filter out unmonitored station traffic.Real-time data collection and analysis improve system efficiency, preventative maintenance, and energy savings. Modulation systems, antenna designs, and power management are just a few of the various ways that must be considered throughout system design and development. IIoT applications also have power, security, and dependability issues. A Low-Power, High-Bandwidth Wireless Communication System for Industrial IoT Applications has a bright future thanks to artificial intelligence and machine learning, 5G networks, new low-power communication technologies, improved security, and blockchain technology. Without this technology, IIoT growth is impossible.

In scientific, military, and industrial sectors, the development of robust and efficient submarine wireless communication links is of enormous interest. Underwater wireless communications can be carried out through acoustic, radio frequency (RF), and optical waves. Underwater optical communication is not a new idea, but it has recently been considered because seawater exhibits a window of reduced absorption both in the visible spectrum and long-wavelength UV light (UV-A). Compared to its bandwidth limited acoustic counterpart, underwater optical wireless communications (UOWCs) can support higher data rates at low latency levels. Underwater wireless communication networks are important in ocean exploration, military tactical operations, environmental and water pollution monitoring. Anyway, given the rapid development of UOWC technology, documents are still needed showing the state of the art and the progress made by the most current research. This paper aims to examine current technologies, and those potentially available soon, for Underwater Optical Wireless Communication and to propose a new perspective using UV-A radiation.

This article discusses about wireless communication technologies such as IEEE 802.15.4, Wireless Sensor Network (WSN), Ultra-High Frequency (UHF) and Near Field Communication (NFC) technologies are described. The part of industry and everyday life could be significantly impacted by Wireless Sensor Networks (WSN). A wireless sensor network (WSN) is a collection of sensor nodes that communicate with one another using wireless technologies. These nodes gather data and send it to the gateway across the Internet, the informal cloud. In a WSN, node-to-node communication may be multi-hop or direct. Every new concept or technology attempts to be integrated into the WSN in order to increase efficiency, improve user experience, and consume less power. Near Field Communications (NFC), a type of wireless networking technology allows to establish simple, secure and interactive communication. iPack is a technology that focuses on integrating NFC into pre-existing systems to create a Wireless Sensor Network (WSN) that supports NFC. Furthermore, data from a sensor node can be transferred to devices with a single touch by using this method. NFC with WSN is a single hop communication. The NFC interface also offers a safe wireless connection.

On many occasions, the wired communications technologies can not meet the actual needs, such as in the operating in the wild or harsh environment. If using communication module built by radio frequency communication chip to achieve the data transmission of two regions of space, take MCU as a control component to achieve the freely data communication docking. This will be a good way to solve the wireless communications problems.

Streszczenie:

Techniques for wireless energy harvesting (WEH) are emerging as a fascinating set of solutions to extend the lifetime of energy-constrained wireless networks, and are commonly regarded as a key functional technique for almost perpetual communications. For example, with WEH technology, wireless devices are able to harvest energy from different light sources or Radio Frequency (RF) signals broadcast by ambient or dedicated wireless transmitters to support their operation and communications capabilities. WEH technology will have increasingly wider range of use in upcoming applications such as wireless sensor networks, Machine-to-Machine (M2M) communications, and the Internet of Things. In this paper, the usability and fundamental limits of joint RF and solar cell or photovoltaic harvesting based M2M communication systems are studied and presented. The derived theoretical bounds are in essence based on the Shannon capacity theorem, combined with selected propagation loss models, assumed additional link nonidealities, diversity processing, as well as the given energy harvesting and storage capabilities. Fundamental performance limits and available capacity of the communicating link are derived and analyzed, together with extensive numerical results evaluated in different practical scenarios, including realistic implementation losses and state-of-the-art printed supercapacitor performance figures with voltage doubler-based voltage regulator. In particular, low power sensor type communication applications using passive and semi-passive wake-up radio (WuR) are addressed in the study. The presented analysis principles and results establish clear feasibility regions and performance bounds for wireless energy harvesting based low rate M2M communications in the future IoT networks.

Rural transportation systems have different features and needs than their urban counterparts. To address safety and efficiency concerns in rural environments, advanced rural transportation systems (ARTS) test and deploy appropriate intelligent transportation systems (ITS) technologies, many of which require communication support. However, wireless communication systems that currently serve urban areas often are not available or suitable in rural environments. Thus, a need exists to identify communication solutions that are likely to address successfully the needs and features of ARTS applications. Current and emerging wireless communications systems and technologies have been systematically assessed with respect to rural ITS applications. Wireless communication functions associated with rural ITS functions are first identified. Then requirements for applicable communication technologies in the rural environment are defined. Existing and emerging wireless communication systems and technologies are reviewed and evaluated by a systematic process of assessing rural ITS wireless solutions. Finally, recommendations for future research and operational tests are offered. The analysis results are expected to benefit rural ITS planners by identifying suitable wireless solutions for different rural contexts.

Wireless communication is a process of transferring information from one place to another place through radio waves. The transfer of information can be either an image or numerical data or voice or video. The design of wireless modules were started to come for a general user in the late 20th century but it has not been accepted in many applications due to its quality degrade over the wired systems. In the beginning of 21st century the improvisation of electronic chips, antenna and microcontroller made the radio wave communication to move forward in a faster way and that made the wireless voice communication as very popular. The paper analyzes the current status of wireless communication in different states and projects the research opportunities by exploring the future expectations of wireless communications.

This work presents a general and introductory review of visible light communication. Visible light communication or VLC refers to wireless communications using a spectral range from 380 to 780 nm for the transmission of information. This part of the optical-electromagnetic range presents some advantages to current wireless radio frequency technologies, as well as several challenges to its development and application. Different visible light communication systems have been developed for indoor, outdoor, domestic, and industrial fields where the luminaire performs two tasks: general lighting and data transmission, since this type of communication has important and valuable applications. Recently, research has been performed to improve each functional block’s performance that composes this kind of communication system. The incursion VLC poses challenges such as LED bandwidth limited by the carrier lifetime, the LED-Driver Linearity, it’s up-link; the general lighting infrastructure to the internet; and the dimming and general lighting performance. It is concluded that the incursion of Visible Light Communication into the already extended spectrum of wireless communications systems will complement and make it less harmful to our environment as international regulation has helped to improve this technology substantially.
