Abstract
- Wireless energy transfer (WET) is a promising technology to fundamentally settle energy and lifetime problems in a wireless sensor network (WSN). In this paper, we study the operation of WSN based on WET using a mobile charging vehicle (MCV) and construct a periodic strategy to make the network operational permanently. Our goal is to decrease energy consumption of the entire system while maintaining the network operational forever. Based on the analysis of total energy consumption, we propose an energy-efficient renewable scheme (ERSVC) to achieve energy saving. Compared to previous schemes where the MCV visits and charges all nodes in each cycle, the MCV only needs to visit a portion of nodes in ERSVC. Numerical results show that our scheme can significantly decrease the total energy consumption with no performance loss. It is also validated that ERSVC can maintain the network operational forever with lower complexity than other schemes, making it more practical for real networks. [ABSTRACT FROM AUTHOR]
