A cooperative mechanism for monitoring in rechargeable wireless mobile sensor networks

The mobile wireless sensor network has much more popular applications in recent years. In the meanwhile, wireless rechargeable sensor networks emerge some technological breakthroughs. However, employing the rechargeable ability to improve the efficiency and lifetime of environment monitoring is a great challenge without cooperation when the rechargeable area is partial of the environment. In this paper, a distributed cooperative algorithm for partial rechargeable mobile wireless sensor network is proposed. The algorithm considers both energy consumption for movement and the resident energy of mobile sensors to cooperate with neighbors for expending the lifetime of environment monitoring. Furthermore, we provide analytical result for obtaining the factors achieving monitoring the environment eternally under some arbitrary parameter settings. The simulations results represent that the efficiency of proposed algorithm.
