A simulation based QoS review of multipath routing protocols for MANET

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/cables 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. In this paper, the QoS comparison of three multipath routing protocols are carried out in terms of five scenario patterns such as RWM, RPGM, MGM, GMM, and PMM in two different traffic patterns such as CBR and TCP using NS2 and Bonn Motion. The multipath routing protocols AOMDV, OLSR and ZRP have been selected for simulation due to their edges over other protocols in various aspects.
