摘　　要：利用超图理论进行建模,从传感器网络的传输层、网络层和MAC层分别进行分析,提出了一种无线传感器网络可靠通信协议RCBHGT,Sink节点发送泛洪,先建立超边路由,然后数据采集节点发送RREQ,建立超边内路由,利用超边内数据确认机制,保证了数据可靠稳定传输,仿真结果表明:在通信环境比较恶劣的情况下,RCBHGT能够使用较低的能耗,保证数据的可靠传输。Modeling by way of hypergraph theory is developed and the transmission, net and MAC of wireless sensor networks is analyzed. A reliable communication agreement of wireless sensor networks, RCBHGT is put forward. By the nodal point, Sink, flooding is sent. A super-edge route is established. The data collecting nodes send RREQ to establish an interior super-edge route, which ensures to reliably transmit the data by using the interior super-edge confirmation mechanism. The simulation result shows that the RCBHGT is able to ensure reliable transmission of data with lower energy consumption in harsh environment.
