农田信息采集系统中传感器网络簇首认证方案研究

Cluster head authentication scheme for WSNs in farmland information collection system

在农田信息采集系统的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在簇形成及稳定阶段对簇首身份进行认证。文章针对簇首认证问题提出了BA-LEACH协议,并通过仿真试验表明协议以较低的能耗增强了系统中分簇传感器网络的安全性。

Clustered sensor networks has been inti＇oduced into WSNs of environmental monitoring system in agriculture production,which has been shown to be increasingly beneficial to increasing system throughput,decreasing system delay,and conserving energy. However,the existing clustered scheme did not provide authentication for cluster head in its setup phase and steady phase. Hence, this study provided BA-LEACH,which was a new security solution for cluster head authentication and could be helpful to enhance the security in clustered sensor networks with comparatively lower energy consumption.
