Abstract :
In MANET, the nodes, configuring a path, act as routers with various mobilities. If the path is broken by nodes´ moving, a new path has to be found again. For this reason, the node with high mobility should be excluded from configuring a path as far as possible. In this paper, we propose an algorithm which excludes nodes with high mobility from constructing a path by collecting and managing the information of mobility. As the result, the proposed algorithm provides more stable paths. In this algorithm, we appends MRecord Field and Relieve Field in the routing table to collect and manage the mobility information by extending current AOMDV In addition, we add Mbl Field to RREP (Route Reply) message to adapt the collected information to configure the path. The performance of the proposed protocol is analyzed, and it is compared with the existing AOMDV by using the ns-2 simulator.
