Book Description
As human sensory structures are often restricted to sensing a small range of visual, hearing, smell, taste, and touch events, the need for extending humans' limited sensory abilities has been a driving force for research, inventions and innovations that have led to discoveries of tools such as wireless sensor nodes. Wireless sensor nodes are inexpensive, multifunctional devices capable of extending humans' limited sensory abilities and they can be used easily to form wireless sensor networks (WSNs), which have a wide range of potential applications. Since wireless sensor nodes are typically battery-powered, a major concern in the design of WSNs is energy conservation as these networks are expected to operate autonomously for long periods. Therefore, this thesis presents a thorough research effort that has investigated ways of improving energy efficiency of WSNs. First, a theoretical model of a WSN's lifetime was established. The model includes collaborative communication and enabled communication techniques to be identified that minimize idle listening and maximise collision avoidance, both of which waste energy. Then the Collaborative Event Driven Energy Efficient Protocol (CEDEEP), which ensures energy efficient operation of one-hop, event-driven WSNs, was introduced. CEDEEP takes advantage of the spatiotemporal correlation of wireless sensor nodes' reporting in event-driven WSNs and uses collaborative communication to conserve energy. The presented analytical results prove the viability of this approach and show that CEDEEP offers considerable improvements in energy efficiency. Subsequently, a novel Energy Efficient Collision Avoidance Method (EECAM) for CEDEEP was proposed. EECAM makes possible higher energy savings by introducing node prioritization based on the distinctive properties of the CEDEEP protocol and event-driven WSN applications. Furthermore, a stochastic model of the one-hop network was developed and the higher energy efficiency of CEDEEP with EECAM was illustrated using the IEEE 802.15.4 and Sift protocols. Therefore, this thesis provides diverse analytical models and offers strong evidence that use of CEDEEP with EECAM, as an event-driven protocol, contributes considerably to the energy efficiency of event-driven WSNs. In this way not only has a superior event-driven protocol been proposed, but a robust basis for future research focused on energy-efficient, event-driven protocols for WSNs has been established.

Book Description
Protocols for sensor networks have traditionally been designed using the best effort delivery model. However, there are many specific applications that need a reliable data dissemination protocol. We present a protocol for efficient and reliable data delivery to all sensor nodes in an energy-constrained, event-driven sensor network in which nodes are mobile or static. The new protocol, SPROID (Scalable Protocol for RObust Information Dissemination), identifies data generated by a unique tag, uses content tables for faster dissemination of information and guarantees reliable dissemination to all nodes in the network within a finite time. SPROID can be made to work with any kind of physical layer requirements, but we focus on the case of a single-channel broadcast medium. Simulations results show that SPROID achieves complete data dissemination in shorter time and with more energy efficiency than SPIN (sensor network protocols using information negotiation).

Book Description
Wireless Sensor Networks came into prominence around the start of this millennium motivated by the omnipresent scenario of small-sized sensors with limited power deployed in large numbers over an area to monitor different phenomenon. The sole motivation of a large portion of research efforts has been to maximize the lifetime of the network, where network lifetime is typically measured from the instant of deployment to the point when one of the nodes has expended its limited power source and becomes in-operational - commonly referred as first node failure. Over the years, research has increasingly adopted ideas from wireless communications as well as embedded systems development in order to move this technology closer to realistic deployment scenarios. In such a rich research area as wireless sensor networks, it is difficult if not impossible to provide a comprehensive coverage of all relevant aspects. In this book, we hope to give the reader with a snapshot of some aspects of wireless sensor networks research that provides both a high level overview as well as detailed discussion on specific areas.

Book Description
The advances in low-power electronic devices integrated with wireless communication capabilities are one of recent areas of research in the field of Wireless Sensor Networks (WSNs). One of the major challenges in WSNs is uniform and least energy dissipation while increasing the lifetime of the network. This is the first book that introduces the energy efficient wireless sensor network techniques and protocols. The text covers the theoretical as well as the practical requirements to conduct and trigger new experiments and project ideas. The advanced techniques will help in industrial problem solving for energy-hungry wireless sensor network applications.

Book Description
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.

Book Description
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.
