Wireless Sensor Networks (WSNs) monitor the environmental conditions that can be used for various applications. They are often encumbered with limited battery energy. Thus, the network lifetime is widely regarded as the performance constriction. Wireless power transfer offers the possibility to remove this performance constriction thus allowing the sensor to remain operational forever. In this paper, the authors discuss the operation of sensor network using this energy transfer technology. They consider a Mobile Charging Node (MCN) which can travel inside the network and charge each node wirelessly. The concept of renewable energy cycle is discussed and offer both necessary and sufficient conditions. The objective is to increase the life time of the sensor network by charging each node wirelessly through this wireless power transfer technology.
