| 摘 要： | 提出了一种基于簇结构的数据收集协议ECDGP(Energy-efficient Cluster-based Data Gathering Protocol).ECDGP使用了一种基于置信度的分簇算法进行簇头竞选,并根据网路覆盖要求选择活动节点,通过控制分簇中活动节点数目,ECDGP减少了能耗和延长了网络生命期.仿真结果表明在能耗和网络寿命上,ECDGP大幅度优于传统的分簇路由算法.

| Abstract: | In this paper,an energy-efficient cluster-based data gathering protocol(ECDGP) is proposed.ECDGP uses a new clustering algorithm based on belief degree for clusterhead election.Furthermore,ECDGP selects the active nodes according to the demand of network coverage.By controlling the number of active nodes in a cluster,ECDGP reduces energy consumption and prolongs the network lifetime.Simulation results have shown that ECDGP significantly outperforms the traditional clustering routing algorithms in terms of e... |
