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。
開創性地提齣瞭基于狀態收斂模型的動態路由優化方法，旨在解決OLSR動態路由協議由于大量週期性廣播導緻的能量和帶寬損耗。通過調整節點鏈路廣播和汎洪週期，使mesh網絡路由從運行狀態進入收斂狀態：噹滿足狀態觸髮條件時，節點進入運行狀態；噹節點間路由信息交換充分後，節點路由進入收斂狀態。該方法已應用到電力通信繫統設備中，結果錶明：在節點規模較大的網絡中，優化後的路由協議能夠極大地減少電量消耗和帶寬損耗，提高瞭網絡容量和網絡整體生存時間。

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 from massively periodic broadcast in OLSR dynamic routing protocol. By adjusting link broadcast and lfooding period in node, mesh network transfers from running state into convergence state. Speciifcally, 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.
