ZigBee is a wireless standard for Wireless Personal Area Networks (WPANs), and it is widely used in industrial, commercial, medical fields where low energy consumption is needed. ZigBee routing protocols should be stable, reliable and low-power. Cluster-Tree routing protocol is a simple and reliable routing protocol used in ZigBee network, and it only takes into account parent-child relationships of nodes, therefore its routing path is single and inefficient. This paper improves Cluster-Tree algorithm by introducing a neighbor table. The improved routing protocol has better performance in less energy consumption and a longer life cycle of entire ZigBee network.

ZigBee technology adaptation and use is an emerging wireless communication technology with low power consumption and long battery life. These technology applications include controlling industrial systems, automating home systems, embedded sensing, and many more. Due to ZigBee's low bit rate and low transmission rate, it is necessary to investigate how ZigBee will perform in a heterogeneous situation using a simulation approach. This paper goes on to describe the design and modelling of mobile ZigBee networks with 5, 10, 15, 20, and 25 nodes to evaluate and compare the performance of this wireless sensor network for star topology networks over time. For the resourceful operation of WSN, mobile ZigBee networks with 5, 10, 15, 20, and 25-star topologies were considered. Certain network parameters such as throughput (bits/sec), delay (sec), end-to-end delay (sec), traffic sent (bits/sec), and traffic received (bits/sec) were explored and compared for smooth WSN operation when ZigBee communication protocol was used and modelled with the OPNET simulator. After evaluating all of the required parameters for various scenarios, an acceptable result was obtained for the mobile ZigBee WSN.

Greenhouse cultivation technology has greatly contributed to the development of agriculture in Malaysia. Understanding how to monitor the greenhouse environment with high efficiency and low power consumption is particularly important. In this research, a wireless sensor network for agricultural greenhouses based on the improved Zigbee protocol is designed. Its hardware consists of various sensors and Zigbee nodes commonly used in agricultural greenhouses. On the basis of this hardware, this research designed the network topology of WMN (Wireless mesh network) by comparing the advantages and disadvantages of various topologies, and combined with this structure, proposed an improved ZigBee routing protocol EMP-ZBR to solve the question regarding energy loss and the network congestion of wireless networks. After testing EMP-ZBR and traditional Zigbee routing protocols, the improved EMP-ZBR protocol is superior to traditional Zigbee routing in terms of the end-to-end average delay, packet delivery rate, routing control overhead and routing discovery frequency, which were optimized about 1.1%, 15.2%, 15.2%, 8.1 ms in different mobile pause times, and 9.8%, 19.3%, 15.7% and 121 ms in different packet sending rates. The agreement proves that EMP-ZBR can more effectively alleviate the impact of congestion and improve the overall performance of the data monitoring system for agricultural greenhouses.

The article considers SMART technology, in particular smart house and basic communication protocols used for data exchange. Smart house technology additionally bears the name «home automation». Home automation in modern conditions allows the user or consumer to flexibly manage and independently configure the system, depending on the requirements of the user. One of the stages of customization of smart home technology is the selection of communication protocol for data exchange within the smart home system.To implement data exchange in smart home technology, it is necessary to properly approach the choice of communication protocols. Smart home technology uses several types of devices: controllers, sensors, acoustics. Since not all devices support existing protocols, there are also unique devices that support several of the existing protocols. There are several protocols used in smart home technology: ZigBee, Z-Wave, Wi-Fi.In this article the analysis of two main wireless protocols operating at high frequencies, namely ZigBee and Z-Wave. Correctly selected protocols implement fast data transmission without loss. In addition, it will be possible to realize the needs of the user or user, which are set by the system.

Le développement des technologies de réseaux de capteurs incite les industries à envisager des alternatives réduisant les coûts et la complexité tout en améliorant la fiabilité. Parmi les solutions sans fil actuelles, la technologie LP-WPAN IEEE 802.15.4/ZigBee dispose des mécanismes et des garanties nécessaires pour une utilisation industrielle. Nous proposons des mécanismes de synchronisation entièrement déterministe permettant l'utilisation du standard IEEE 802.15.4 en mode balisé dans un réseau maillé, ainsi qu'une méthode de routage adaptative « AODV en » pour les messages transmis dans un réseau étendu. En premier lieu, nous analysons la technologie IEEE 802.15.4/ZigBee, plus particulièrement sa capacité à conserver son comportement déterministe et économe en énergie dans une architecture de réseau maillé. Cette étude met en évidence plusieurs insuffisances du standard. Notre contribution consiste à palier à ces manques par une synchronisation centralisée réactive aux changements de topologie, esquivant les collisions de balises et de GTS. Ces modifications seront apportées au niveau de la sous-couche MAC. En second lieu, aucun des protocoles de routage (couche 3 du modèle ISO) actuellement les plus utilisés, ne prennent en compte simultanément les critères indispensables au contexte des communications dans un environnement industriel à fortes contraintes sur la consommation et sur le temps. Nous proposons un mécanisme de routage réactif adaptatif recherchant les routes optimisant la durée de vie des noeuds du réseau contraints énergétiquement, et basé sur l'optimisation conjointe du délai et de la consommation. Pour cela, nous avons analysé et évalué la consommation de chacun des noeuds sans fil autonomes utilisant le standard. Nous avons ainsi proposé des informations de délai et de niveau de charge de la batterie de chacun des noeuds, prises en considération dans notre mécanisme de routage adaptatif. L'ensemble de nos propositions sont validées en utilisant diverses méthodes dont les réseaux de Petri temporisés, la simulation et le prototypage. Les résultats obtenus sont exposés à la suite de chacune de nos contributions.

Au sein de l'Internet des Objets, le secteur de la maison connectée est en plein essor. Pour quelques dizaines d'euros, chacun peut s'équiper de solutions domotiques intelligentes commandables à distance. Ces écosystèmes sont cela dit vulnérables à des attaques variées en raison A) d'une conception essentiellement guidée par le coût, générant des objets contraints sans implémentation de sécurité viable possible, B) de l'utilisation par ces objets de protocoles de communication sans-fil hétérogènes, dispersant les efforts de sécurisation, et C) de la gestion de ces objets par des consommateurs non-experts, adeptes du « setup and forget ».Contrairement à l'informatique traditionnelle où les solutions de protection sont répandues, nous faisons le constat de l'absence de proposition commerciale équivalente dans la maison connectée. Dans cette thèse, nous nous interrogeons sur les conditions de l'adoption à grande échelle de solutions de sécurité de type Systèmes de Détection d'Intrusion (IDS), visant à protéger les objets contraints déjà déployés. Ainsi, une première contribution recense les caractéristiques des maisons connectées pour les croiser avec des taxonomies d'IDS, afin de proposer les critères qualitatifs d'une solution de sécurité domestique réaliste.Par la suite, afin de faciliter la conception d'IDS, une deuxième contribution met à disposition de la communauté scientifique un jeu de données Zigbee, participant à la fourniture d'outils couvrant les principaux protocoles de la maison connectée. Toutes les trames échangées par 10 objets pendant 10 jours ont été capturées par 4 sondes distribuées dans un domicile-test. Des attaques ont été introduites afin d'établir et comparer différentes stratégies de détection. Outre une redondance des données de couche MAC, le jeu de données tire son originalité de l'extraction par chaque sonde du RSSI (Received Signal Strength Indicator) de chaque trame. Cette grandeur de couche physique, accessible à peu de frais dans les technologies sans-fil, permet de participer à l'identification de nœuds fixes. Par la suite, on peut imaginer d'identifier robustement chaque objet par une empreinte de couche physique faite d'un tuple de RSSI, complexe à imiter par un attaquant.Enfin, dans une troisième contribution, nous exploitons le jeu de données pour proposer un IDS détectant les attaques d'usurpation d'identité, favorisées par le fait que des piles de protocoles n'intègrent que peu ou pas d'authentification sur leur couche MAC. Pour les détecter, la cohérence de l'identifiant de couche MAC et de l'empreinte précédente à base de RSSI peut être considérée mais ce n'est plus possible quand les environnements sont sans cesse redessinés par les habitants qui y évoluent, les RSSI devenant volatiles. En fournissant des séries temporelles de RSSI en entrée d'un algorithme d'apprentissage non supervisé, nous établissons pour chaque couple (objet, sonde) un modèle des séquences RSSI normales. Les déviations par rapport au modèle permettent de détecter une attaque. Les métriques de détection obtenues, très intéressantes en regard de la faible complexité de l'architecture initiale envisagée, ainsi que les évaluations de l'autonomie et du coût de la solution laissent entrevoir une diffusion de tels systèmes dans les maisons connectées
Within the Internet of Things, the smart home sector is booming. For a few tens of euros, everyone can be equipped with smart-home automation solutions that can be controlled remotely. However, these ecosystems are vulnerable to various attacks due to A) an essentially cost-driven design, generating constrained devices with too few resources for viable security implementations, B) the use by these devices of multiple wireless communication protocols, dispersing security efforts, and C) the management of these devices by non-expert consumers, following a “setup and forget” policy.Unlike traditional IT where protection solutions are widespread, we note the absence of an equivalent commercial proposal in smart-home environments. In this thesis, we question the conditions for a large-scale adoption of security solutions such as Intrusion Detection Systems (IDS), aiming at protecting constrained devices already deployed. Thus, a first contribution identifies the characteristics of smart homes to cross them with IDS taxonomies, in order to propose the qualitative criteria of a realistic domestic security solution.Subsequently, in order to facilitate the design of IDS, a second contribution provides the scientific community with a Zigbee dataset, participating to the availability of tools covering the main protocols found in smart homes. All the frames exchanged by 10 devices during 10 days were captured by 4 probes distributed in a test house. Attacks have been introduced in order to establish and compare different detection strategies. In addition to MAC layer data redundancy, the dataset derives its originality from the extraction by each probe of the RSSI (Received Signal Strength Indicator) of each frame. This physical layer feature, accessible easily in most wireless technologies, allows to participate to the identification of fixed nodes. Later, one can imagine identifying each device more robustly by a physical layer fingerprint made of a tuple of several RSSIs, a complex combination to imitate by an attacker.Finally, in a third contribution, we exploit the dataset to propose several IDSs detecting spoofing attacks, favored by the fact that several protocol stacks integrate little or no authentication on their MAC layer. To detect them, the consistency of the MAC layer identifier and the previous RSSI-based fingerprint can be considered, but this is no longer possible when the environments are constantly redrawn by the evolving inhabitants, as the RSSI becomes volatile. By providing RSSI time series as input to an unsupervised learning algorithm, we establish for each (device, probe) pair a model of normal RSSI sequences. Deviations from this model help detect an attack. The obtained detection metrics, which are very interesting given the low complexity of the initial considered architecture, as well as the evaluations of the autonomy and cost of the solution, suggest the spread of such systems in smart homes

Rede de computadores são elementos fundamentais no processo de comunicação. Esses componentes exigem o acompanhamento constante de suas tarefas e são administrados por sistemas de informações que coletam os dados diariamente, para orientar os analistas de suporte na correção das falhas na infraestrutura e a ferramenta utilizada na gestão de recursos de rede de computadores é o protocolo SNMP. As infraestruturas de geração de energia elétrica também são elementos complexos e necessitam de acompanhamento. São utilizados sistemas de informação que disponibilizam dados para os usuários e responsáveis técnicos para avaliarem o funcionamento e corrigir as possíveis falhas. As redes de computadores e os sistemas de geração distribuídas estão convergindo para o ambiente do usuário, e as ferramentas de gestão são importantes são mecanismos na gestão da produção e consumo de energia elétrica. Assim, este trabalho tem como objetivo desenvolver um sistema de monitoramento on line para sistema de microgeração fotovoltaica utilizando o protocolo de rede de computadores Single Network Management Protocol (SNMP) para realizar a interface de comunicação com as variáveis de medições elétricas e meteorológicas. O desenvolvimento do projeto compõe dois componentes: hardware e software. O software é composto de dois módulos um para ser utilizado na Web, aplicações Desktop para uso em computadores que suportem sistemas operacionais como o Windows, Linux ou Mac e em dispositivos móveis. As funcionalidades programadas são cadastros das informações para o funcionamento do sistema, relatórios e gráficos que disponibilizam as informações ordenadas em vários níveis, diariamente, semanalmente, anualmente. Nos componentes de hardware foram utilizados cinco microcontroladores Atmel AVR, (Arduino) todos ligados à sensores e programados para a leitura de geração e consumo de energia elétrica e variáveis ambientais, como velocidade do vento, radiância solar, temperatura e níveis de chuva no período, e controle do sistema de bombeamento com duas motos bombas. Todos os experimentos foram realizados na central de microgeração distribuída fotovoltaica (MGD-PV) do Sítio Modelo da fazenda Lageado e no Laboratório de Energias Renováveis do Departamento de Engenharia Rural, nas Faculdades de Ciências Agronômicas da UNESP, campus de Botucatu. O laboratório de Energias Renováveis é o Servidor do sistema e as distâncias são muito variáveis entre todos os microcontroladores, de 32 metros a 260 metros e para realizar o processo de coleta dos dados nos diversos pontos e suprir essa distância foi necessário a construção e configuração de uma infraestrutura de comunicação baseada nas tecnologias ZigBee, para conectar os cincos microcontroladores. Os dados são coletados em intervalos regulares de cinco minutos, às variáveis ambientais são acompanhadas vinte e quatro horas por dia e às variáveis de geração de energia elétrica entre sete da manhã e dezessete horas da tarde. Os dados foram coletados entre setembro de 2016 e fevereiro de 2017. Os componentes de hardware e de software apresentaram rendimentos satisfatórios no processamento das informações através da interface criada pelo protocolo SNMP na comunicação e nas transmissões dos dados gerados pelos sensores, na configuração e mapeamento os objetos para construção da MIB para serem utilizados nas medições elétricas e variáveis ambientais.
Computer networks are fundamental elements in the communication process. Such components demand constant supervision of their tasks and are managed by information systems, which daily collect data to guide support analysts when correcting glitches in the infrastructure. Protocol SNMP is the tool used for managing resources of the computer network. The infrastructures of electric energy generation are also complex elements and require monitoring. Information systems are utilized, which provide data to users and technical professionals, so they can evaluate functioning and correct possible errors. Computer networks and systems of distributed generation are converging towards the user’s environment, so, management tools are important mechanisms in the control of production and consumption of electric energy. Thus, this work aims at developing an online monitoring system for photovoltaic microgeneration using the Single Network Management Protocol (SNMP) to perform the communication interface with the variables of electrical and metereological measurements. The project development is composed of two elements: hardware and software. The software consists of two modules: one to be used on the Web, Desktop apps for use in computers that can carry operational systems such as Windows, Linux or Mac and one to be used in mobile devices. Programmed functionalities include information register for the functioning of the system; reports and graphs that show information ordained in several levels, daily, weekly and annually. As to hardware, we used five microcontrolers Atmel AVR, (Arduino) connected to sensors and programmed for reading the production and consumption of electric energy as well as environmental variables, such as wind speed, solar radiance, temperature and rain levels during the period and control of the pumping system with two motor pumps. All experiments were carried out at the Distributed Photovoltaic Microgeneration Central (MGD-PV) on a Model Farm and at the Renewable Energies Laboratory of the Agronomy College at UNESP, in Botucatu. The Renewable Energies Laboratory is the server of the system and the distances among all microcontrolers vary from 32 to 260 meters. Therefore, in order to collect data from several locations and neutralize such distance, we needed to build and configure a communication infrastructure based on ZigBee technologies to connect the five microcontrolers. Data are collected during five-minute intervals; environmental variables are followed twenty four hours a day and the variables of electric energy production between 7am and 5pm. Data were collected between September 2016 and February 2017. Hardware and software components showed satisfactory performance at processing information through the interface created by the SNMP protocol regarding communication and transmission of the data generated by sensors as well as on the configuration and mapping objects for the construction of the MIB to be used in electrical measurements and environmental variables.

This research studies the security challenges in IoT devices. At first, security challenges have been described and then specifically the security of communication protocols in the IoT has been addressed. Finally, among different communication protocols, ZigBee and Z-Wave protocols have been chosen for this study. The criterion for choosing these two protocols is the level of security they provide for IoT devices to protect them against unauthorized access and hacking. Security, frequency, power consumption and data rate are the characteristics that have been discussed in the review of these two protocols. In the end, a comparison of the various features of these two protocols clarified that the security of IoT devices in each of these protocols depends on the type of the IoT device, the required range and other requirements, however, in most cases the ZigBee protocol showed more security than Z-Wave.

It is innovative with regard to the monitoring of vehicles operating in permanent ways, assessing real-time performance. This assessment is intended to assist in preventive and corrective operation and maintenance of rail vehicles in order to improve the quality of services provided. This system has as main objective to enable a constant evaluation of factors which influence in the performance of the trains, as actual speed and pressure on the stock air suspension, so as to allow intervention strategies, thus avoiding a partial or total degradation of the transport services to passengers. To perform real-time telemetry, a network of wireless sensors, using ZigBee technology was set up in the way of traffic. The network made the capture and transmission of data collected from a train to the base station where a program installed on a personal computer is instructed to receive and send the collected data through an Ethernet network to a central monitoring system. The base station system acts as a data server providing information to a monitoring system installed in the Operational Control Center (OCC) of the Brazilian Company of Urban Train - Recife (CBTU / METROREC). The monitoring system installed in OCC is responsible for managing the storage and display of data received. It will display data and graphics in real time allowing traffic controllers monitor the functioning of the train and detect possible problems. The system also stores the data in a database for further studies.
Este trabalho apresenta o desenvolvimento de um sistema telemétrico dinâmico de veículos em malhas metroferroviárias que utiliza a transmissão de sinais via radiofrequência, de acordo com protocolo de comunicação padrão internacional. Compõese de microcontroladores e um rádio transceptor, que, quando acoplados a sensores, captam e transmitem os dados em questão, funcionando como transdutores sem fio. Tratase de tecnologia modular de baixo custo, baixo consumo de energia, segura e capaz de monitorar diversas variáveis simultaneamente. É uma técnica inovadora no que se refere ao monitoramento de veículos que circulam em vias permanentes, avaliando em tempo real o seu desempenho. Essa avaliação pretende-se que auxilie nas ações preventivas e corretivas de operação e manutenção dos veículos rodoferroviários, a fim de melhorar a qualidade dos serviços prestados. Esse sistema tem como principal objetivo permitir uma constante avaliação de fatores que influenciam o desempenho dos trens, como velocidade real e pressão nas bolsas de ar da suspensão, de forma a possibilitar estratégias de intervenção, evitando assim uma degradação parcial ou total dos serviços de transporte prestados aos passageiros. Para realizar a telemetria em tempo real, montou-se na via de tráfego uma rede de sensores sem fio, com tecnologia ZigBee. Essa rede efetuou a captação e envio dos dados coletados em um trem até a estação base onde um programa instalado em um computador pessoal fica encarregado de receber e enviar os dados obtidos, por meio de uma rede ethernet, a um sistema central de supervisão. O sistema da estação base atua como um servidor de dados disponibilizando informações para um sistema de supervisão instalado no Centro de Controle de Operacional (CCO) da Companhia Brasileira de Trens Urbanos Metrô do Recife (CBTU/METROREC). O sistema de supervisão instalado no CCO é responsável por gerenciar o armazenamento e a visualização dos dados recebidos. Ele exibirá os dados e gráficos em tempo real permitindo aos controladores de tráfego analisar o funcionamento do trem e detectar possíveis problemas. O sistema também armazenará os dados em um banco de dados para a realização de estudos posteriores.

This thesis is focused on the industrial environment. This study aims to understand the difficulties wireless communications have when performing in these types of environment with a specific standard (and protocol) Zigbee. These difficulties are due mainly to the physical effects and interferences as well the electromagnetic waves from these wireless transmission signals can suffer. The background of this project is to analyze how industries can implement wireless sensor networks (using Zigbee standard) for their factories in order for them to be beneficial i.e. reliable or if it is possible. Industries normally tend to keep in the path of the old fashioned way i.e. wired systems which are more robust and can cope with the hard system requirements. Some study on these environment effects (interference as well) is performed. The results show how this (Zigbee) sensor network could be or should be implemented in order to have the best performance (disposition of devices, type of environment considering only industrial environments, etc.). Specifically, these results show that Zigbe wireless sensor networks are limited to some conditions in order to obtain the desired reliability. These conditions are that these networks must be performed in absorbing environments, LoS disposition of devices, not too long diatance between devices and not other networks in the same area using the same frequency band. The limitation of absorbing environments is because the dispersion effects in the (highly) reflective environments are critically damageful for the link. The limitation of the other devices operating in the same frequency band in a close area is due to the fact that Zigbee has no frequency diversity. Last but not least, the limitations to LoS and not too long maximum range (approximately 50 meters) are related since the range would be (much) lower than 50 meters if the communication was in NLoS disposition of devices. The noise in this environment is also studied and modeled. The results show that as the impulsive index (which is ameasure of the number of impulses that reach the receiver in a certain unit of time) takes larger values, the distribution approximates that of a Gaussian and as A takes lower values the reults show an impulsive characteristic. The Probability of error is computed for values of A less than 1, where the impulsive characterstic is shown, and as A takes larger values the error is greater.

Traditional Wireless Sensor Network (WSN) solutions have been deemed insufficient to address the requirements of freight railroad companies to implement real-time monitoring and control of their trains, tracks and wayside equipment. With only ZigBee-based elements, the transmission capabilities of WSN devices are limited in terms of coverage range and throughput. This leads to severe delay and congestion in the network, particularly in railroad scenarios that usually require the nodes to be arranged in linear chain-like topology. In such a multi-hop topology to communicate from one end of a train to the locomotive — and due to ZigBee’s limited communication range — data needs to be transmitted using a very high number of hops and thus generates long delays and congestion problems. To overcome this drawback, we have proposed a heterogeneous multi-hop networking approach called “Hybrid Technology Networking” (HTN). In HTN we combined Wireless Local Area Network (WLAN) technologies like WiFi, which provide improved communication range and higher data rates, with low-power communication technologies like ZigBee. This significantly reduces the number of hops required to deliver data across the network and hence solves the issues of delay and congestion, while also achieving superior enery efficiency and network lifetime. The sensor nodes are logically divided into clusters and each cluster has a WiFi “gateway”. All intra-cluster communication is achieved via IEEE 802.15.4 and ZigBee protocols, while all inter-cluster communication utilizes WiFi protocol standards. To implement our proposed technology in railroad networks, we are designing hardware prototypes and simulation models to evaluate the functionality and performance of our HTN solution, which is designed around a dual network stack design governed by the HTN protocol. This ensures full compliance with IEEE and industry communication protocols for interoperability. Since no simulation tools that seamlessly combine both WSN and WLAN technologies in a single module exist, we wrote our own simulation environment using OPNET. In this paper, we have provided information of implementing the HTN protocol in OPNET and the simulation results for different scenarios relevant to railroad operations. These results will demonstrate the efficacy of our proposed system as well as provide the baseline data for testing the hardware devices in live networks. Under simulated traffic and channel conditions and device configurations, we observed a decrease of 77.27% in end-to-end delay and an increase of 69.70% in received data volume when using HTN compared to ZigBee-only multi-hop networks, simulated over 14 railcars in railroad-relevant scenarios.

Real-time monitoring of various components of a railcar such as wheel bearing temperature, brake line status, integrity of transported goods and many more has become a key focus area of research for the North American freight railroad industry. The ability for timely detection of abnormalities and impending failures prevents costly accidents, the potential loss of life and damage to the environment. Monitoring also increases overall operational efficiency, reliability and safety of freight railroads. Wireless Sensor Networks (WSN) are an obvious choice for implementing such a monitoring scheme. The accumulated data from various sensors distributed throughout each railcar along the length of the train is transmitted wirelessly using multi-hop transmissions to the locomotive for alerting and monitoring. From there, this information is also transmitted to dispatch centers for further analysis and recording. ZigBee technology based on the IEEE 802.15.4 standard is a popular choice among WSN communication protocols, owing to its low cost and low power requirements. ZigBee performance degrades severely in the long chain-like topology characteristic of the railroad application environment. This effectively disqualifies ZigBee as a candidate technology for such railcar monitoring deployments. To overcome these issues with ZigBee deployments for freight train monitoring we developed our Hybrid Technology Networking (HTN) approach [5–7]. HTN leverages both ZigBee and Wi-Fi communication to achieve reliable communication along an entire freight train. Railcar monitoring nodes are grouped into smaller clusters, within which we utilize ZigBee for its low-power operation and report to each cluster’s gateway node. The gateway nodes of all the clusters on a train communicate using Wi-Fi, to benefit from the high throughput and long communication range. This tiered architecture also results in a drastic reduction in overall hop count for end-to-end communication. In this paper we present HTNMote, a hardware platform that we are developing and employing for real-world evaluation of the HTN protocol. We also present results from our field tests of the HTNMotes at the Transportation Technology Center (TTCI) facility in Pueblo, Colorado, operated by the US Association of American Railroads (AAR). The results show that the use of HTN improves performance of the network by at least an order of magnitude compared to a ZigBee-only network. This paper details the design of our HTNMote platform, present the test setup and results, as well as conduct an in-depth analysis of the obtained results as they relate to railroad operations.

This paper presents the development and performance study of a two-level wireless sensor network (WSN) for structural health monitoring (SHM). The lower-level network adopts low-power ZigBee protocol whereas the higher-level network employs high speed WiFi communication for long distance data transmission. To promote distributed data processing and damage diagnosis, the higher-level sensor nodes are designed to possess high computational capabilities. A reliable data transmission mechanism is implemented in the lower-level ZigBee network. To reduce the power consumption and quickly respond to extreme events, an event-driven monitoring approach is proposed. The impact of the coexistence of ZigBee and WiFi on the system’s performance is also studied.

The North American freight railroad industry continuously strives towards improvements in the safety and security of freight transportation. One key effort focuses on the use of Wireless Sensor Networks (WSN) technologies to monitor and report mechanical and electrical component status for each railcar in real-time, as well as the status of the transported goods themselves. This allows real-time monitoring of railcar components such as air pressure, wheel bearing temperature, brake failure, wiring integrity, refrigeration unit failure, boxcar door opening, the detection of radioactive materials, dangerous substance leaks, and much more. The aggregated sensor data is transmitted to the locomotive, dispatch centers or regional offices for early fault detection and accident prevention. Our previous work [1] has shown that ZigBee technology based on the IEEE 802.15.4 faces numerous obstacles when applied to freight railcar monitoring. To address these problems our team proposed an alternate approach called Hybrid Technology Networking (HTN), which combines the benefits of ZigBee for low-power short-range communication and WiFi for high-performance long-distance communication between HTN sensor clusters. In this paper, we present our simulation results using our HTN protocol. We compare and discuss the performance of the ZigBee-only network environment with the proposed HTN and demonstrate the advantages offered by HTN. We also discuss our prototype sensor hardware platform using the HTN protocol and provide an outlook of the future work planned for HTN.
