【 摘 要 】

A mobile Ad-hoc NETwork (MANET) is wireless network composed of mobile nodes that are dynamically and randomly located in such a manner that the interconnections between nodes are capable of changing on a continual basis. In order to facilitate communication within the network, a routing protocol is used to discover routes between nodes. The primary goal of such an ad-hoc network routing protocol is correct and efficient route establishment between a pair of nodes so that messages may be delivered in a timely manner. Route construction and maintenance should be done with a minimum of overhead and bandwidth consumption. The ABR is a source-initiated protocol and is working on the assumption of stable route from the source to the destination node. Maintenance for the route when the destination node moves will be performed in backtracking scheme starting from the immediate upstream node from the destination. If this process results in backtracking more than halfway to the source, it will discontinue and a new route request will be initiated from the source. In the case if the Source Node moves, then the Source Node will invoke a route reconstruction because the ABR is source-initiated protocol. This study presents an enhanced method for the route re-construction in case the source, the intermediate, or the destination node changes its location by giving more active role to the moving node in maintaining the established route.
