摘要
针对无线传感器网络数据信息传输可靠性,提出一种无线传感器网络中基于协作通信的分簇路由算法。该算法主要对分簇、簇间路由和簇内路由三个阶段进行了设计,依据信噪比寻找满足网络数据传输可靠性的最佳路由,实现源节点和目的节点之间的协作通信。仿真结果表明,无线传感器网络中基于协作通信的分簇路由算法能够有效地优化网络路径,提高频谱利用率,增强数据信息传输的可靠性。
Aimed at the improvement of data transmission reliability in wireless sensor networks (WSNs), a cooperative communication based clustering routing algorithm is proposed in this paper. This algorithm includes three phases of clustering, routing between clusters and routing in cluster, which are able to determine the optimal data path to satisfy the data transmission reliability based on the radio of signal and noise, and then realize the cooperative communication between source node and destination node. The simulation results show that the cooperative communication based clustering algorithm in WSNs can effectively optimize the data path in network, and improve the efficiency of fre- quency spectrums, and then enhance the reliability of data transmission.
