Title：Charging Planning of Wireless Rechargeable Sensor Networks

Abstract

The network lifetime of wireless sensor networks (WSNs) is based on their battery power so that the sensors will be run out of power eventually. Therefore, ensuring the energy efficiency of WSNs has become an indispensable issue. Nevertheless, since no energy efficiency mechanisms can be regarded as a sustainable solution, the wireless rechargeable sensor network (WRSN) has been proposed, with the chargers deployed to provide needed power for the sensors. Deployment cost will increase when the number of the chargers increases, but it can help the whole wireless sensor network avoid being crashed. In other words, they have the trade-off relationship; as well, many metrics may impact the final policy for chargers deployment such as distance, transmission radius, power requirement of the sensors, and so on. It means that the chargers deployment problem is very complex and may not obtain the results in exponential time. In this speech, some effective solution for charger planning will be given. I will also introduce some popular topics related WSNs. It is hoped that this speech will help students interested in the field.
