分簇WSN基于有效负载握手的远程身份验证

Remote identity authentication based on active-load handshake of clustering WSN

为解决传感器节点资源受限以及通信链路易出错的问题,给出一种分簇无线传感器网络中基于有效负载握手的远程身份验证协议。使用集中式基于簇的分层无线传感器网络选出最优百分比的簇头,授权允许其与邻近节点通信,通过最小化节点的能量消耗实现网络负载平衡;每个簇头发挥一个服务器的作用,在每个传递消息的有效负载内保证数据认证和交换,对附近节点进行身份验证以形成簇。实验结果表明,所给协议在安全性、抵御攻击的鲁棒性、握手持续时间、平均能量消耗和网络平均吞吐量性能方面均优于现有的imp-LEACH协议和sec-LEACH协议。

To solve the problems of resource limitation of sensor nodes and error-prone communication chain,a remote identity authentication based on active-load handshake of clustering wireless sensor network was proposed.The cluster head with the optimal percentage was selected using the centralized cluster-based hierarchical wireless sensor network,which was authorized to communicate with neighboring nodes,and the network load balance was realized by minimizing the energy consumption of the nodes.Each cluster head acted as a server,ensuring data authentication and exchange with each payload that delivered the message,and authenticating nearby nodes to form clusters.Experimental results show that the proposed protocol is better than the existing imp-LEACH protocols and sec-LEACH protocols in the aspects of security,robustness,handshake duration,ave-rage energy consumption and average network throughput.
