基于随机游走的无线传感器网络覆盖洞修复
RANDOM WALK-BASED COVERAGE HOLES RECOVERY IN WSN
摘要
Abstract
In recent years,wireless sensor network has gradually become the focus of research.Because of the energy depletion or failure of the sensor node in WSN,original covered area will not be covered by any nodes,which is known as the coverage hole.In view of the cov-erage hole problem,we proposed the random walk-based algorithm for recovering coverage hole by mobile nodes.Through adding mobile nodes in wireless sensor network,the algorithm uses the random walk means which integrates the energy consumption and delay to guide the mobile node to find coverage holes,and then fill the holes.Through simulation experiment the result proved the effectiveness of the algorithm, the path of coverage hole searched out by mobile node is optimal in terms of energy and delay.关键词
