一种基于状态收敛模型的OLSR协议优化方法

An Optimization Method of OLSR Protocol Based on State Convergence Model

开创性地提出了基于状态收敛模型的动态路由优化方法,旨在解决OLSR动态路由协议由于大量周期性广播导致的能量和带宽损耗。通过调整节点链路广播和泛洪周期,使mesh网络路由从运行状态进入收敛状态:当满足状态触发条件时,节点进入运行状态;当节点间路由信息交换充分后,节点路由进入收敛状态。该方法已应用到电力通信系统设备中,结果表明:在节点规模较大的网络中,优化后的路由协议能够极大地减少电量消耗和带宽损耗,提高了网络容量和网络整体生存时间。

An optimization method of dynamic routing based on state convergence model was originally proposed in this paper which deals with losses of energy and bandwidth resulting fiom massively periodic broadcast in OLSR dynamic routing protocol. By adjusting link broadcast and flooding period in node, mesh network transfers fiom running state into convergence state. Specifically, when trigger condition is met, node enters running state; when routing information between nodes is fully exchanged, node routing enters convergence state. This method had been applied to equipment of electric power communication system. Results demonstrate that in network with large-scale nodes, the optimized routing protocol not only highly reduces power consumption and bandwidth loss, but improves network capacity and network living time as well.
