    Preface With an ever increasing demand of new wireless sensing applications, energy has been the primary concern for wireless sensor networks. In particular, energy conservation has been studied extensively to extend network lifetime. A variety of approaches have been proposed in literature that can elongate network lifetime to some extent. However, with limited energy storage, sensor’s battery would deplete eventually and replacing those batteries requires tremendous human efforts. In this book, we describe a new approach to replenishing sensor’s battery via wireless charging without wires or plugs. We start with a detailed overview of the recent developments in wireless charging technologies and their applications in wireless sensor networks to highlight the advantages and disadvantages. We then provide a new hierarchical network architecture that adopts a mobile vehicle for wireless charging. We name such networks Wireless Rechargeable Sensor Networks (WRSNs). Based on this network architecture, we discuss several principles from theoretical aspects, and design communication protocols and recharge schedul- ing algorithms to maintain perpetual network operations. We also give network performance evaluation results in various criteria such as nonfunctional node percentage, network latency, and energy overhead. The state-of-the-art wireless charging technology covered in this book would help readers understand existing challenges and inspire future research to improve energy efficiency and network lifetime for wireless sensor networks.
