Comparative Analysis of Unipath and Multipath Reactive Routing Protocols in Mobile Ad hoc Network

collection of wireless mobile nodes and each of these nodes can be considered as an individual portable devices. Current unipath routing protocols result in performance degradation in mobile networks due to the unreliability of wireless infrastructure and mobility of nodes. Multipath routing protocol is an attractive alternative that distributes the traffic among several good paths instead of routing all the traffic along a single best path for highly error prone and resource depleted network environments. Frequent link failures are common in MANET due to node’s mobility and use of unreliable wireless channels for data transmission. Due to this, multipath routing protocol becomes an important research issue. Among the reactive protocols, AODV is a reactive routing protocol.Ad-hoc On-demand Multipath Distance Vector Routing (AOMDV) protocol is an enhancement part of the AODV protocol for computing multiple loop-free and link disjoint paths. Due to the frequently changing topology, routing in ad-hoc networks can be viewed as a challenging issue
