Abstract
AODV is a reactive routing protocol that sets up routes between source and destination nodes as and whenneeded. The performance of AODV protocol depends on the choice of certain parameters including route requestretries which is, by default, set as two in the corresponding RFC. In the present work, the effect of Route RequestRetries (RRR) on a set of performance metrics viz. Normalized Routing Load (NRL), Average End-to-End Delay(AEED), Packet Delivery Ratio (PDR) and Throughput has been investigated for a linear ad hoc network of fivenodes. Three different scenarios have been investigated wherein middle node is made to remain stationary, mobilewith low mobility and mobile with high mobility. Mobility of the middle node is found to be having significanteffect on the performance of such linear ad hoc networks. RRR has no influence on the performance of linear adhoc network of stationary nodes. However, RRR is having significant effect on the performance of linear ad hocnetwork if a node is made mobile. Performance of such linear ad hoc network is also affected by the choice ofduration of simulation.
