Switching method for wireless mesh network

Abstract

The invention relates to the technical field of the wireless mesh networks and discloses a switching method for the wireless mesh network. The method comprises the following steps: (A) adopting a minimum dominating set algorithm to select an agent router in a plurality of mesh network routers and updating the agent router at specific time; (B) selecting one optimal mesh network router as a first mesh network router to establish association when a mobile client accesses the mesh network and sending association information to the agent router by the first mesh network router; and (C) when the mobile client is switched due to movement, selecting a novel mesh network router as a second mesh network router to establish association and sending novel association information to the agent router and the first mesh network router by the second mesh network router. By the switching method for the wireless mesh network, which is disclosed by the invention, the cost of updating the association information due to switching is reduced and the efficiency that the wireless mesh network process mobility is improved. 本发明涉及无线网状网络技术领域，公开了一种用于无线网状网络的切换方法，所述方法包括步骤：A.在多个网状网路由器中采用最小支配集算法选择代理路由器并在特定时间更新代理路由器；B.移动客户端接入网状网络时选择一个最佳的网状网路由器作为第一网状网路由器建立关联并由第一网状网路由器将关联信息发送到代理路由器；C.移动客户端因移动而发生切换时选择一个新的网状网路由器作为第二网状网路由器建立关联并由第二网状网路由器将新的关联信息发送到代理路由器和第一网状网路由器。通过本发明公开的一种用于无线网状网络的切换方法，降低了因切换而导致的关联信息更新的代价，提高了无线网状网络处理移动性的效率。
