基于可信度的簇间多跳LEACH算法

A LEACH Topology Algorithm with Multi-Hop between Clusters Based on Trust Evaluation

通过分析低功耗自适应集簇分层型协议(LEACH)和基于可信度的低功耗自适应集簇分层型协议(TE-LEACH)算法的不足,提出一种基于可信度的簇间多跳低功耗自适应集簇分层型协议(TEM-LEACH)算法.该算法既考虑簇头节点传输数据的可信度,又引入网关节点构建路由主干网,保证数据经过最少的跳数传输到基站,有效地延长无线传感器网络生存时间,增加了LEACH算法的适用范围.

By analyzing the deficiencies of low energy adaptive clustering hierarchy（LEACH） and LEACH based on turst evaluation（TE-LEACH）,this paper proposes a LEACH algorithm with multi-hop between clusters based on trust evaluation（TEM-LEACH）.It considers not only the trust evaluation of cluster heads between data transmission,but also building the routing bakcbone network through gateway nodes.The improved scheme can guarantee the data transfer with minimal hop to the sink,extend the survival time of the network effectively and enhance the scope of application.
