This book provides a systematic treatment of the theoretical foundation and algorithmic tools necessary in the design of energy-efficient algorithms and protocols in wireless body sensor networks (WBSNs). These problems addressed in the book are of both fundamental and practical importance. Specifically, the book delivers a comprehensive treatment on the following problems ranging from theoretical modeling and analysis, to practical algorithm design and optimization: energy-efficient clustering-based leader election algorithms in WBSNs; MAC protocol for duty-cycling WBSNs with concurrent traffic; multi-channel broadcast algorithms in duty-cycling WBSNs; and energy-efficient sleep scheduling algorithms in WBSNs. Target readers of the book are researchers and advanced-level engineering students interested in acquiring in-depth knowledge on the topic and on WBSNs and their applications, both from theoretical and engineering perspective.

Mobile, Wireless and Sensor Networks available in PDF, EPUB and Kindle. Wireless networking covers a variety of topics involving many challenges. The main concern of clustering approaches for mobile wireless sensor networks (WSNs) is to prolong the battery life of the individual sensors and the network lifetime. For a successful clustering approach, the need of a powerful mechanism to safely elect a cluster head remains a challenging task in many research works that take into account the mobility of the network. In Mobile, Wireless and Sensor Networks: A Clustering Algorithm for Energy Efficiency and Safety, the authors use an approach based on computing of the weight of each node in the network as the proposed technique to deal with this problem. They present a virtual laboratory platform (VLP) of baptized mercury, allowing students and researchers to make practical work (PW) on different aspects of mobile wireless sensor networks. The authors’ choice of WSNs is motivated mainly by the use of real experiments needed in most college courses on WSNs. These usual experiments, however, require an expensive investment and many nodes in the classroom. The platform presented here aims at showing the feasibility, the flexibility, and the reduced cost using the authors’ approach. The authors demonstrate the performance of the proposed algorithms that contribute to the familiarization of the learners in the field of WSNs. The book will be a valuable resource for students in networking studies as well as for faculty and researchers in this area.

This book was released on 2012. Energy-efficient Protocols and Systems for Wireless Sensor Networks and Smart Environments available in PDF, EPUB and Kindle. In a wireless sensor network, small computing devices, called sensors, sense the surrounding environment and relay the sensed data to a base station over a multi-hop wireless network, eventually processing them en-route. Wireless sensor networks and other devices, such as smartphones, smart meters, and smart appliances, cooperate in smart environments to obtain information about the environment, and then use this information to improve the experience of the users. Since most of these systems rely on battery power, there is a need for energy-e cient solutions for their operation. The objective of this dissertation is to design algorithms and protocols to improve the energy efficiency of such systems, and validate them using mathematical analysis, software simulations, and testbed experiments. In the first part of the dissertation, we look at two fundamental problems in wireless sensor networks: localization and duty cycling. In the area of localization, we describe a novel protocol for duty cycling wireless actor and sensor networks, and present a mathematical analysis based on the coupon collector's problem and the theory of coverage processes, as well as simulation results. Our analysis and results show that the proposed protocol achieves the user-requested localization accuracy while maximizing the sleep time of sensor nodes. As far as duty cycling is concerned, we present novel Markov chain-based randomized schemes, and discuss the probabilistic analysis, as well as the experiments we conducted on Sun SPOT sensors. These results show that our proposed schemes reduce the sleep latency, while not a ecting other performance metrics such as the energy e ciency, or vice versa. In the second part of the dissertation, we shift our focus to smart environments, and present our research work on data fusion and visualization aimed to provide lay users with actionable information. We introduce a framework, called FuseViz, to leverage already existing data sources such as smartphones, online databases and services, and wireless sensor networks, while addressing the challenges posed by large, live, heterogeneous, and autonomous data streams. We demonstrate the concepts behind our framework with a case study in building energy e ciency, and introduce E2Home, a Web-based application for this problem developed on top of the framework. Preliminary experiment results for the proposed E2Home system not only show that the actionable information can be easily computed, but also demonstrate energy savings of about 10%. Finally, we conclude our dissertation with an overview of a system-level energy model, built using data from the above-mentioned sources, that can be tailored for each home, its location, and residents, and can help further minimize energy consumption.

This book was released on 2009. Energy Efficient Communication and Rate Control Algorithms for Wireless Sensor Networks available in PDF, EPUB and Kindle. Sensor networks provide applications in many diverse areas. This is for the simple fact that they are reliable, flexible, easily deployable and highly cost-effective. Smart sensors can provide such diverse services as detecting signs of machine failures, sensing earthquakes, onset of flooding and even provide a warning system for potential terrorist attacks. Because the sensors are untethered and battery powered, these networks have to maintain a high yield to the energy spent per sensor device. These yields translate into mainly throughputs and packet latencies while keeping the energy usage at the minimum. In this work, we look at the communication level energy usage within the sensor networks and propose novel scheme for channel access optimized for energy consumption and rate control algorithms for traffic engineering and congestion control in wireless sensor networks. The first involves a novel medium access protocol for wireless sensor networks. The protocol is based on exploiting the periodicity inherent in carrier sensing schemes like CSMA/CA combined with a relaxed time-access arbitration regime among the competing nodes. Transmission and reception of data frames are made to be strictly receiver triggered events which makes it possible to bring down idle-listening drastically. The protocol also provides a way to make the channel access collision-free among the two-degree neighbors. PMAC requires no additional control signaling and no network-wide synchronization. The protocol does not seek to make any tradeoff for the gains in energy efficiency with latency or throughput. It presents high-energy efficiency and throughput improvement in low as well as high-traffic scenarios of sleeping. In the second part, we propose novel rate-control algorithms for the wireless sensor networks. There has been a growth in personal area network technologies like Bluetooth etc to support various applications that require multimedia level QoS in a high interference environment. Applications such as voice data traffic, file transfers, periodic synching of electronic devices within the range of 10m-15m requires sophisticated yet simple channel access techniques that accommodate different QoS requirements of these applications. In this context, the new rate control algorithms were designed that reduces the interference and maximized the throughput and reliability parameters such as packet success rates, packet latency and aggregate throughput per flow. Moreover, the rate control algorithm also takes into account the fairness issues among the competing flows in terms of the bandwidth-share.
