Abstract

A wireless sensor network consists of many lowpower, low-cost nodes which can perform sensing, computing, and send short messages over short distance. In respect that sensor nodes are powered by batteries, energy would be very important for wireless sensor work. In this paper, we proposed an efficient relay node displacement mechanism which considers each node's energy consumption and analysis the lifetime per unit cost.
