摘　　要：针对幻影路由算法中源节点距离基站节点较近时安全周期低的问题,提出基于随机虚拟环的无线传感器网络源位置隐私保护算法。初始时由源节点随机产生一个以基站为中心的虚拟环,利用源节点到基站的直线方程和虚拟环方程确定预期幻影源节点,为选择幻影源节点提供依据;通过数据包在虚拟环上转发随机的角度,确定第二个幻影源节点。理论分析表明算法安全周期与通信开销呈正相关。仿真结果表明,该算法能有效诱导攻击者偏离真实路径,提高安全周期。Aiming at the problem of low safety period when the source node is close to the base station node in the phantom routing algorithm,a source location privacy protection algorithm for WSNs based on random virtual ring is proposed.At the beginning of the algorithm,the source node randomly generated a virtual ring centered on the base station.The expected phantom source node was determined by using the linear equation and virtual ring equation,which provided a basis for selecting the phantom source node.The second phantom source node was determined by the random angle of packet forwarding on the virtual ring.Theoretical analysis shows that the algorithm security period is positively related to the communication overhead.The simulation results show that the algorithm can effectively induce adversary to deviate from the real path and improve the security period.
