Ramprasad Kumawat, Vinay Somani . Comparative Study of On-demand Routing Protocols for Mobile Ad-hoc Network. International Journal of Computer Applications. 27, 10 ( August 2011), 6-11. DOI=10.5120/3339-4597
A Mobile Ad-hoc Network (MANET) is a dynamic wireless network that can be formed without the need for any pre-existing infrastructure in which each node can act as a router. One of the main challenges of MANET is the design of robust routing algorithms that adapt to the frequent and randomly changing network topology. A variety of routing protocols have been proposed and several of them have been extensively simulated or implemented as well. In this paper, we compare and evaluate the performance metrics of three types of On- demand routing protocols- Ad-hoc On-demand Distance Vector (AODV) routing protocol, which is unipath, Ad-hoc On-demand Multipath Distance Vector (AOMDV) routing protocol and Dynamic Source routing (DSR) protocol. This paper investigates all these routing protocols corresponding to packet delivery fraction (pdf), throughput, normalized routing load and end to end delay. The ns-2 simulation results showed that AODV has always low routing load compared to AOMDV in both static and dynamic network for each set of connections. AOMDV provided better results at high pause time but worst in case of end to end delay. We have also seen that, DSR performed well in terms of end to end delay in both static and dynamic networks.
