摘要
文章研究分簇式无线传感器网络中簇头之间的协同传输问题,簇头负责收集簇内各个节点的数据,经由其他各簇头的共同协作将数据发送至汇聚中心,簇内普通节点不参与协作过程。针对了两种协作通信方案,从网络吞吐量和系统中断概率的角度进行了理论分析与比较。最后,通过数学仿真分析验证了选择中继方案优于全中继方案。
In this paper, the cooperative transmission of cluster leader based on clustering type wireless sensor networks is discussed. During the transmission process, each cluster leader collects the data from each node, and send data to Cluster center with the cooperation of other cluster leader. Ordinary nodes do not participate in the collaborative process. Two collaborative communication solutions are compared and analyzed in terms of the network throughput and system outage probability. At last, simulation proves that the selective relay solution is better than all relay solution.
