Abstract
As the performance of mobile nodes advances, the ad hoc network will work with many mobile nodes. In such network, the route between the source node and the destination node is elongated, and then the route maintenance might become more difficult due to the topology change. Therefore, we have proposed Route-Split Routing (RSR) scheme for large mobile ad hoc network environments. RSR sets up multiple Subroute Management Nodes (SMNs) on the route between the source node and the destination node and divides the route into multiple subroutes. Since the subroute between two adjacent SMNs is locally managed, RSR has less overhead for the route maintenance and achieves the higher performance than AODV. In addition, RSR becomes tolerant to the multiple concurrent link failure because the route is repaired by each SMN on a subroute basis. RSR could provide higher data packet delivery ratio, but has high overhead because the route becomes longer as the subroute can be locally repaired and separately. Therefore, this paper proposes three mechanisms to enhance the performance of RSR for large mobile ad hoc network environment and then evaluates it through simulation environment. As a result, the enhanced RSR with three proposed mechanism can decrease the total control overhead by 50 percent with high data packet delivery ratio.
