The Shortest Path Diffusion Mechanism under Real-time Reliability Network Routing Method

针对网络通信实时性、可靠性的要求,提出一种最短路径扩散机制下实时可靠性网络路由选择方法。依据链路质量对加入网络的节点构建逻辑路径,形成树状结构。将某节点与其他节点之间的可用物理链路看作辅助路径,得到Mesh形网络拓扑结构。分析了最短路径扩散机制,利用最短路径扩散机制对网络中全部节点构建最短路径信息。介绍了网络交通流和交通引力场模型,考虑节点对交通流的引力作用,将传输路径看作影响引力的指标,通过交通引力场实现网络路由选择。实验结果表明,所提方法在保证网络实时可靠性的同时,可减少能耗,降低数据丢包率,提高网络吞吐量。

According to the real-time and reliability of network communication requirements,a shortest path diffusion mechanism under the real-time reliability of network routing method was proposed,based on the link quality of the construction of a logical node join the network path,forming a tree structure.The physical link between a node and other nodes can be regarded as an auxiliary path to get the topology of mesh network.The shortest path diffusion mechanism is analyzed,and the shortest path information is constructed for all nodes in the network.The model of network traffic flow and traffic gravitation field is introduced,and the transmission path is considered as the index to influence the gravity.The experimental results show that the proposed method can reduce the energy consumption,reduce the packet loss rate and improve the network throughput.
