Improving the QOS in MANET by Enhancing the Routing Technique of AOMDV Protocol

A MANET is an interconnection of mobile devices by wireless links forming a dynamic topology without much physical network infrastructure such as routers, servers, access points or centralized administration. The multipath routing protocols establish efficient communication within the network by discovering multiple routes between a pair of source and destination in order to have load balancing to satisfy Quality of Service (QoS) requirements. The aim of this work is to modify the existing MANET reactive Multipath routing protocol Ad hoc On-demand Distance Vector (AOMDV) using drop minimization under MAC error control technique like collision minimization, dynamic queue scheme etc. In AOMDV routing we apply multipath base data sending scheme but that protocol not fulfill QoS so here we apply drop analysis base and find out pitfall of the AOMDV and after that we apply various drop minimization technique like rate base data sending scheme, queue base congestion control etc. and improve the performance of the network. A narrative Multipath QoS Aware Routing Protocol based on AOMDV is proposed to support packet delivery ratio, routing overhead minimization and UDP analysis constraints.
