Observation of AODV routing protocol’s performance at variation in ART value for various node’s mobility

Abstract

ART is a fixed parameter in AODV routing, which tells that how long route state information should be kept in the routing table. However, as per this simulation study, an optimal value of ART is the function of node’s mobility. Therefore, the presented research work attempts to analyse the impact of variation in Active Route Timeout (ART) value on the Quality of Service (QoS) metrics for different values of node’s mobility in AODV routing of the ad hoc network. This research work concludes that the lower values of ART perform better, especially at higher node’s mobility. Moreover, it is also concluded that the network performs better in terms of throughput at ART = 1 s and in terms of delay as well as jitter at ART = 0.5 s, which is less than its default QualNet ART value (i.e. 3 s). © Springer International Publishing Switzerland 2016.
