Abstract: The mobile nodes in a network which can communicate with each other through a radio wave without any specific infrastructure is widely known as Mobile Ad-hoc Network(MANET). MANET has a number of routing protocols. The popular routing protocols so far are Dynamic Source Routing (DSR), Destination Sequenced Distance Vector (DSDV), Ad-hoc On-demand Distance Vector (AODV) and Temporally-ordered Routing Algorithm (TORA) routing protocol. Among them the AODV routing protocol meets efficiently with the ad-hoc network specification. For last few years routing protocols of mobile ad-hoc networks (MANETs) were simulated as a function of mobility, number of nodes, and size of the network but not as a function of route maintenance parameters such as Active Route Timeout (ART) and Delete Period Constant (DPC=n) with moving source-destination (node) pairs in network as well.
