RWSNs中基于效用最大化的数据收集方案研究
Scheme of utility maximization data collection in rechargeable WSNs
摘要
Abstract
The various applications of wireless sensor networks(WSNs)are restrained by the sensor′ battery in severe envi⁃ronment,and the WSNs face various difficulties in data collection,so the wireless energy transfer technology used to replenish the energy of sensor cluster is proposed. Aiming at the wireless rechargeable senor cluster deployed in severe environment,an effi⁃cient data collection scheme is proposed. In the scheme,the unmanned aerial vehicle(UAV)is used to arrive at the site of the sensor cluster in severe environment,after that the data is collected,and the sensors corresponding to the cluster are charged. In this paper,the utility function of data collection is defined to describe the data collection problem as an optimal problem taking utility maximization of data collection as the target,and the greedy algorithm based on bilateral preference matching and unilateral preference matching algorithm are proposed to solve the above problems. The theoretical analysis and simulation experiment re⁃sults show that the matching relation of UAV and sensor cluster determined with the proposed greedy algorithm can generate the optimal solution of making data collection utility maximum,and can realize the efficient collection of sensor data.关键词
