基于虚拟环的源位置隐私保护路由协议

针对无线传感器网络(WSNs)中源节点位置隐私保护问题,提出了基于随机虚拟环的源位置隐私保护路由协议,可以避免失效路径的产生,同时,随机变化的虚拟环将路由路径扩展到源节点所在的环形区域内,极大地增加了路由路径的随机性和多样性,使得攻击者难以根据路由路径推测出源节点所在位置.仿真结果表明:在有限时延的情况下,协议明显提高了源位置隐私保护能力.

Routing protocol of source-location privacy protection based on virtual ring

Aiming at problem of source node location privacy protection in wirless sensor networks(WSNs),a routing protocol for source-location privacy protection based on random virtual ring is proposed.The protocol avoids generation of failure path and extends routing path to the annular region which source node resided with the random virtual ring.It greatly increases the diversity and randomness of the routing path,and make it hard for an attacker to estimate the location of the source node according to the routing path.The simulation results show that under limited time delay,the ability of source-location privacy protection is increased obviously with the protocol.
