Performance Evaluation of AOMDV, AODV and DSR Reactive Routing Protocols using NS-2

Abstract- Mobile Ad hoc networks (MANET) are frequently changing network topology, using multi-hop wireless links without any fixed infrastructure. Reactive Routing is important for Ad hoc network in terms of resource, robustness and efficiency when mobility is high and links get disconnected frequently. Performance of three reactive routing protocols for mobile Ad hoc network including Ad hoc On-demand Multi path Distance Vector Routing (AOMDV), Ad hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR) is evaluated using Network Simulator (ns-2). Performance is evaluated with respect to fraction of packets delivered and end-to-end delay for Common Bit Rate (CBR) traffic model. Relative strength, weakness and applicability of each reactive routing protocol to different situations are studied and evaluated.
