摘要
针对全移动传感器网络覆盖空洞的修复以及网络寿命最大化问题,研究并设计了一种基于可信信息覆盖模型的传感器节点重定位协议。该协议在可信信息覆盖模型下的信息网格的概念下,设计一种局部信息网格结构,通过使用移动最近的冗余传感器节点修复覆盖空洞区域来维持网络的完全覆盖。仿真结果表明,所设计的协议与现有的协议传感器节点重定位协议相比,可以有效减少重定位的移动能量消耗,明显提升全移动传感器网络的工作寿命。
Network working time is one of the issues that wireless sensor networks must consider.Based on the confidence information coverage model,a new sensor node relocation protocol is designed to improve the network working life of the mobile sensor network by reducing the mobile energy of the sensors involved in repairing the coverage hole.Under the concept of an information grid based on a confidence information coverage model,the protocol designs a local information grid structure for publishing and retrieving distance sensitive data,such as sensor location information,and repairing holes by using the nearest redundant sensor nodes to maintain the complete network coverage.The simulation results show that compared with the existing sensor node relocation protocol,the designed protocol can effectively reduce the mobile energy consumption and significantly improve the working life of the entire mobile sensor network.
