摘要
在无线传感器网络通信中,针对已有幻象路由协议可能因失效路径而降低源节点安全时间的问题,提出了一种基于最短距离路由的无线传感器网络源节点位置隐私保护路由算法。该路由算法包括初始化过程、改进的源节点幻象路由策略和避开源节点可视区的最短距离路由策略。理论分析和实验结果表明,与已有的幻象路由协议相比,该路由算法生成的幻象节点能较好地远离源节点,并且提高了源节点的安全时间,可以较好地保护源节点位置的隐私安全。
After introducing the background and significance of the research on the source location privacy protection in wireless sensor network, an improved routing algorithm for wireless sensor network source node location privacy pro- tection based on the minimum path routing is proposed on the problem of low security time of source node in PUS- BRF,PSRMPN and LPBMR. And then, the initialization process, the improved strategy of source node phantom routing and the minimum path routing strategy to avoid the visual area of source node about the new routing algorithm are detailedly explained. Theoretical analysis and experimental results show that the improved routing algorithm has higher security time of source node and does better in protecting source location privacy in wireless sensor network.
