Abstract :
Because of high mobility and resource constrains in mobile ad hoc network (MANET) environment, a lot of challenges are encountered in effective routing such as quality of service (QoS). In this paper, the ad hoc on-demand distance vector (AODV) routing protocol is revised by calculating the corresponding QoS provision values to find the best routes and applying the mechanism of carrier sense in IEEE 802.11b to obtain the available bandwidth. Simulation showed that using QoS parameters in route discovery process can significantly reduce end-to-end delay and increase packet delivery ratio under conditions of high load and moderate to high mobility, though the routing load of AODV is slightly less than that of the proposed protocol. Comparison between original routing protocol and the improved algorithm is carried out by using NS-2.
