Abstract: Compared with the traditional table-driven routing protocols, the AODV routing protocol reduces routing overhead in dynamic maintenance of routes. However, with AODV, network performance degrades rapidly with the increase of offered load. In this paper, we propose a simple and effective modified version of AODV, named Traffic-Balanced AODV (TB-AODV). In this protocol, each node, basing on its local MAC load status decides whether it can accept routing requests from other nodes or not. Simulation results show that TB-AODV achieves better overall performance than AODV.
