碩士 === 逢甲大學 === 通訊工程所 === 97 === The architecture of Wireless Mesh Network had combined the merits of Ad Hoc Mode and Infrastructure Mode; it is built by several Wireless Access Point (WAP) and Wireless Node (WN). The WAPs in Mesh network can communicate and route by defined Protocol for each other by Ad Hoc’s interface, WNs and WAP use Infrastructure Mode to setup association and forward packets from WNs. However in the independent wireless mesh network, as a result of terminal node''s frequent migration, causes the route way expiration frequently. The AODV route agreement is excessively slow to the expiration route way reaction rate, causes the material transmission the delay time to lengthen, to solve the related problem, this article proposed the terminal multi-way backup calculating method. Affiliation AODV-BR (Backup Routing) unites the auxiliary way backup calculating method, this research strengthened when the terminal node migration, the fast renewal transmits route''s mechanism, and then proposed AODV-AMBR (Associativity Multi-Backup Routing) hereinafter referred to AMBR. Is auxiliary using terminal node''s neighbor node, in addition the terminal node own multi-way backup, simultaneously considers the current way relaying node in the way choice the capacity, the choice average capacity are few and transmission speed route. May cause to transmit the material mobile termination node, the immediate renewal route way, and reduces the material transmission the detention. Prove to the new route protocol on planning to adopt NS2 simulation platform in this plan, with observation of different parameter. To improve the conveyance efficiency of this network system. To offer concrete contribution for development of wireless mesh network structure.
