基于超图理论的无线传感器网络可靠通信协议
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。
Abstract
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.
