Research of Recharging Scheduling Scheme for Wireless Sensor Networks Based on Cuckoo Search

摘要

Wireless sensor networks (WSN) have been in widely use due to its prominent capability of data sensing and processing. However, the lifetime of WSN is constrained because of the limited battery energy in each sensor node. Fortunately, recent breakthrough in the area of wireless energy transfer technology has created a new dimension to prolonging the lifetime of WSN. In this paper, we firstly introduce the conception and requirements of cyclic energy conservation in conditions of rechargeable WSN via Wireless Charging Vehicle (WCV). Then, in order to enhance the utility of charging, optimization of the minimal occupied time of WCV achieved by Cuckoo Search is carried out, hence leading to the prior solution of TSP and essential properties of cyclic energy conservation. Furthermore, the optimal solution of cyclic energy conservation in WSN is presented and the simulation result of the proposed scheme is given. Lastly, a conclusion of our research is drawn and a potential outlook of research is given as well.
