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
A large-scale distributed wireless sensor network is composed of a large collection of small low-power, unattended sensing devices equipped with limited memory, processors, and short-range wireless communication. The network is capable of controlling and monitoring ambient conditions, such as temperature, movement, sound, light and others, and thus enable smart environments. Energy efficient data disseminationis one of the fundamental services in large-scale wireless sensor networks. Based on the study of the data dissemination problem, we propose two efficient data dissemination schemes for two categories of applications in large-scale wireless sensor networks. In addition, our schemes provide spatial-based multi-resolution data dissemination for some applications to achieve further energy efficiency. Analysis and simulation results are given to show the performance of our schemes in comparison with current techniques.

Book Description
In recent years, wireless sensor networks (WSNs) have attracted significant attentions from both academia and industry, and are widely proposed for a broad range of applications, where data collection is often a core service to facilitate sensed data being forwarded to a central base station for further processing. Powered by batteries and using wireless communications, a WSN is more flexible than its wired counterpart. However, wireless losses/collisions may be prevalent when nodes communicate with each other. Moreover, the lifetime of a WSN largely depends on that of individual nodes, which is further constrained by the generally non-replenishable batteries. Energy-efficiency thus becomes a critical concern that must be addressed. In practice, using WSNs for data collection can be broken into three major stages, namely, deployment, message dissemination and data delivery. The deployment stage focuses on best deploying the network in the sensing field. In the message dissemination stage, network setup/management and/or collection command messages are disseminated from the base station to all sensor nodes, where the challenges lie in how to disseminate messages with low transmission costs and latencies in the presence of error-prone wireless communications. The data delivery stage fulfills the main task of data collection. Based on the information indicated by the message dissemination stage, sensed data are gathered at different nodes and delivered to the base station, with application-specified Quality-of-Service requirements to be fulfilled. In this thesis, we tackle the design issues for each of these stages. For the deployment stage, we propose to use relay nodes for traffic relaying and suggest that the deployment should be aware of the data traffic to be collected by specific applications. We then discuss how to efficiently disseminate message in a low duty-cycle scenario, where nodes alternate between active and dormant states to conserve energy and thus extend the network lifetime. To address the traffic accumulation problem, particularly in the data delivery stage, we take a case study on high-rise structure monitoring application and propose to use elevators to facilitate data collection. Our analysis and experimental results offer systematic solutions toward reliable and energy-efficient data collection by WSNs.

Book Description
A wireless sensor network (WSN) is often deployed in a harsh or hard-reach area and is required to operate for a long period time to collect and route sensed information. Since each sensor node is battery-powered, prudent energy-efficient mechanisms have been proposed to extend the network life-time. However, recharging (or replacing) the battery is ultimately unavoidable. In this data dissemination strategy, we consider energy harvesting (or scavenging) with environmental energy sources, such as solar, wind, or vibration. We extend the original sensor protocols for information via negotiation (SPIN) and propose an energy harvesting aware data dissemination strategy for energy rechargeable wireless sensor networks, called Green-SPIN. In Green-SPIN, each node intermittently harvests energy and judiciously changes its communication range. We compare the performance of three data dissemination schemes as a function of number of nodes and the communication range through extensive simulation: Flooding, SPIN with broadcast (SPIN-BC), SPIN with reliability (SPIN-RL), and Green-SPIN.
