摘要:

设计了一种基于多移动节点和路径规划的传感器网络覆盖的修复策略。该机制通过对节点消耗能量的分析,采用遗传算法计算出移动节点的合理移动路径,可以最大可能地对普通节点进行及时修复,最大程度地避免由于传感器节点死亡带来的覆盖空洞。用随机过程在数学上证明了算法的收敛性。通过仿真实验的测试证实,所设计传感器节点修复机制和对移动节点的路径规划的求解算法能有效地预防节点死亡带来的覆盖空洞问题。

Abstract:

A repairing strategy for the coverage of the sensor network based on multi-mobile nodes and path planning is designed.Such mechanism can ultimately repair common nodes in a timely fashion via energy consumption analysis of the nodes by using genetic algorithm to calculate the reasonable moving path of the mobile nodes,which can avoid cov-erage holes caused by the death of sensor nodes at its best.The global convergence the designed algorithm is proved by stochastic process.Simulation experiments have proven the effectiveness of the designed mechanism and the relevant solution algorithm.

Key words: wireless sensor network, coverage hole, repair; lifetime, multi-mobile node
