Comparative Study of Unipath and Multipath Routing Protocols

An ad hoc wireless network can be described as collection of nodes that interact among themselves without any centralized authority. In an ad hoc network node movement results in dynamic topology and link failure. Thus, routing become a challenging task and many routing protocols have been proposed to overcome various challenges of routing in ad hoc networks. In this paper we compare AODV and AOMDV routing protocols. The AODV is a unipath routing protocol and AOMDV is a multipath version of AODV. In this article our objective is to analyze both the protocols under various scenarios and metrics with different parameters such as cbr rate, simulation time and packet size and show their effect on performance measures. Comparison between AODV and AOMDV is evaluated based on Packet Delivery Ratio, Throughput, Drop count and End-to-End Delay. All analysis is done using NS2 simulator.
