Load Balanced AODV - An Improvement of Performance and Fairness

In this paper we focus on the performance improvement of reactive routing protocol of wireless ad-hoc networks by considering traffic load and geographical information of the network that are involved in routing procedure. A mobile node that already has or potentially will have excessive routing duty should act as a relaying node with relatively low probability. We use three parameters that are available in AODV: the size of routing table L, the expiration time of each route entry i in the table Δt_i, and the number of neighbors of each node j involved in routing nj. Simulation results from ns-2 show that our scheme gives significant improvement in terms of packet delivery ratio, end-to-end delay, and arrival jitter.
