摘要
在无线传感器网络(WSN)中,安全问题已经成为一个重要的问题。但在现有的WSN路由协议中,很多仅考虑节能因素而没考虑安全因素,而那些专门为安全而设计的路由协议则一般开销较大算法复杂,难以在WSN中实施。为解决问题,提出了一种安全节能的分簇路由协议SEEC,它综合了安全高效的SEER路由协议以及基于剩余能量的非均匀分簇路由协议两者的优点:节点仅仅需要完成数据传感等简单功能,而由基站完全控制簇的管理和路由选择,不仅节约了节点能量,而且防止了恶意节点的攻击;另外,对节点的非均匀分簇,更进一步节约了能量。分析和仿真结果表明,方案不仅能够提供很好的安全性,而且有效地延长了网络生存时间。
In the wireless sensor networks （ WSN）, security has become an important problem. In the existing wireless sensor network routing protocols, some of them only concern energy cost, not taking security issues into account; and the cost of security routing protocols is too much. In order to solve the problem, the paper introduces a new routing protocol SEEC ： Secure and Energy - Efficient Clustered Routing protocol. SEEC has strongpoints of both the SEER and uneven clustering routing protocol. In SEEC the base station does the cluster management as well as route selection, the node only completes charge sensing. This method not only can defend attacks but also is energy saving. In addition, the paper divides all the sensing nodes into clusters, and then it can save more energy. Analysis and simulation results show that this new routing protocol not only can defend usual attacks in wireless sensor network well but also can prolong the network lifetime efficiently.
