基于名誉机制的无线传感器网络安全路由协议
摘要
针对无线传感器网络中TEEN路由协议安全性不高的问题
在TEEN的基础上引入了名誉机制
提出了一种安全高效的路由协议TEENRM。TEENRM在每个节点上构建一个名誉表
在簇首选举前
先对簇内节点名誉度进行验证
当节点的名誉度值低于限定值时
禁止该节点参与簇首的选举
以此建立多个安全的簇
抵御HELLO泛洪攻击与选择转发攻击
提高网络的路由安全。仿真结果表明:改进后的协议较原协议有较高的分组投递率和较低的端到端时延
并能延长网络的生存时间。
Abstract
To improve the security of TEEN routing protocol in wireless sensor networks(WSNs)
the reputation mechanism is introduced into TEEN and a safe and high efficient routing protocol
threshold sensitive energy efficient sensor network protocol based on reputation mechanism(TEENRM) is presented.In TEENRM
a reputation table is constructed on each node
through which the node’s reputation degree can be validated before the election of cluster heads.When a node’s reputation degree is lower than the limited value
it will be isolated and forbidden to be cluster head.In this way
safe clusters will be formed and the routing security is improved because the network is resistant to HELLO flooding and selective forwarding attacks.The Simulation results show that
the improved protocol has better delivery ratio and lower end-to-end time delay
and prolongs the surviving time of WSNs.
