An Upgraded Load-Aware Routing Protocol for Ad Hoc Networks

Minimum-hop strategy of normal routing protocols for ad hoc wireless networks doesn't consider the load of the network, which may lead to network congestion and degrade performance of the network thereafter. In order to solve this problem, this paper proposes a simple and effective modified version of AODV-Load-Aware AODV (LA-AODV), in which, each node decides whether or not to accept routing requests from other nodes according to its local link layer load. Simulation results show that the upgraded LA-AODV performs better than AODV, which bring the overall improvement on the network performance.
