摘要
针对SPIN协议的不安全性,采用声誉机制,提出了一种安全的无线传感器网络路由协议R-SPIN。该协议是对洪泛转发的改进,通过在网络中为节点增加信誉值参数,使得节点在选择下一跳节点的时候不仅要考虑节点的剩余能量,还要考虑节点信誉值,降低了攻击节点被选为下一跳节点的可能。对其性能进行分析和仿真,仿真结果表明,与SPIN协议相比,R-SPIN显著地延长了网络的生命周期,提高了包传输率,降低了包丢失率,提高了网络的安全性。
For the insecurity of SPIN protocol, a secure wireless sensor networks routing protocol R - SPIN was presented. The protocol was based on the reputation system. It increased the credibility parameter of each node in network. When it chose the next hop, it took both the energy of the node and the credibility of the node into account, so it could reduce the possibility that the attack nodes were chosen as the next hop. The protocol was simulated and its performance was analyzed. Compared with SPIN protocol, the results showed that R - SPIN prolonged the lifecycle,improved the packet delivery ratio and also reduced the drop ratio. It improved the network security.
