无线传感器网络层次路由安全通信研究

Research on Hierarchy Routing Secured Communication in WSN

在无线传感器网络中引入分簇结构,可提升系统吞吐量、降低系统延迟以及节省能量。但已有的分簇方案并未较好地实现簇的安全通信。针对此问题,提出SSCRA协议,借助覆盖半径来确定簇规模成簇,簇间采用多跳路由。为实现安全通信,簇内和簇间分别利用簇密钥和簇间密钥来保障数据包的加密和认证性。仿真实验表明该协议以较低的能耗增强了分簇传感器网络的安全性。

Clustered sensor networks have been introduced into WSN,which have been shown to be increasingly beneficial in increasing system throughput,decreasing system delay,and conserving energy.However,the existing clustered scheme did not provide secured communication in cluster.Hence SSCRA is provided,which determine the size of a cluster and organize the cluster by service radius,use multi-hop routing in clusters.To realize secured communication,SSCRA use keys in Intra-Cluster and Inter-Cluster to guarantee the Encryption and authentication.Simulation experiments indicate that the new scheme can enhance the security in clustered sensor networks with comparatively lower energy consumption.
