A Sensor Redeployment Approach Based on Energy-balanced in Wireless Sensor Network

摘要

A sensor redeployment method approach based on energy-balanced in wireless sensor network is proposed in this paper. The more realistic probabilistic detection model with false alarm rate is used in wireless sensor networks. Construct the network state function considering the joint detection probability and residual energy of nodes, and search for coverage holes by threshold segmentation, then determine the position of optimal candidate node through Max-avg and deploy new nodes to repair coverage holes. Simulation results show that the proposed method could find and repair coverage holes effectively through redeploy new nodes and achieve higher network state value which ensure effective access information and optimize the network performance then prolong the network lifetime.
