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
Wireless sensors and sensor networks (WSNs) are nowadays becoming increasingly important due to their decisive advantages. Different trends towards the Internet of Things (IoT), Industry 4.0 and 5G Networks address massive sensing and admit to have wireless sensors delivering measurement data directly to the Web in a reliable and easy manner. These sensors can only be supported, if sufficient energy efficiency and flexible solutions are developed for energy-aware wireless sensor nodes. In the last years, different possibilities for energy harvesting have been investigated showing a high level of maturity. This book gives therefore an overview on fundamentals and techniques for energy harvesting and energy transfer from different points of view. Different techniques and methods for energy transfer, management and energy saving on network level are reported together with selected interesting applications. The book is interesting for researchers, developers and students in the field of sensors, wireless sensors, WSNs, IoT and manifold application fields using related technologies. The book is organized in four major parts. The first part of the book introduces essential fundamentals and methods, while the second part focusses on vibration converters and hybridization. The third part is dedicated to wireless energy transfer, including both RF and inductive energy transfer. Finally, the fourth part of the book treats energy saving and management strategies. The main contents are: Essential fundamentals and methods of wireless sensors Energy harvesting from vibration Hybrid vibration energy converters Electromagnetic transducers Piezoelectric transducers Magneto-electric transducers Non-linear broadband converters Energy transfer via magnetic fields RF energy transfer Energy saving techniques Energy management strategies Energy management on network level Applications in agriculture Applications in structural health monitoring Application in power grids Prof. Dr. Olfa Kanoun is professor for measurement and sensor technology at Chemnitz university of technology. She is specialist in the field of sensors and sensor systems design.

Book Description
With the rapid growth of technology in society, communication networks have become a heavily researched topic. Implementing these advanced systems is a challenge, however, due to the abundance of optimization problems within these networks. The use of meta-heuristic algorithms and nature-inspired computing has become a prevalent technique among researchers for solving these complex problems within communication networks. Despite its popularity, this specific computing technique lacks the appropriate amount of research that is needed for professionals to grasp a definite understanding. Nature-Inspired Computing Applications in Advanced Communication Networks is a collection of innovative research on the methods and applications of natural computation techniques and algorithms within communication systems such as wireless sensor networks, vehicular adhoc networks, and internet of things. While highlighting topics including mobile sensor deployment, routing optimization, and sleep scheduling, this book is ideally designed for researchers, network professionals, computer scientists, mathematicians, developers, scholars, educators, and students seeking to enhance their understanding of nature-inspired computing and its solutions within various advanced communication networks.
