COMPARISON OF DYMO, AODV, DSR AND DSDV MANET ROUTING PROTOCOLS OVER VARYING TRAFFIC
Anuj Gupta, Jatinder Kaur, Sandeep Kaur · 2011
Routing in a MANET is challenging because of the dynamic topology and the lack of an existing fixed infrastructure. In such a scenario a mobile host can act as both a host and a router forwarding packets for other mobile nodes in the network. Routing protocols used in mobile ad hoc networks (MANET) must adapt to frequent or continual changes of topology, while simultaneously limiting the impact of tracking these changes on wireless resources. The DYMO protocol intended for the use by mobile nodes in wireless multihop ad hoc networks. It can adapt to the changing network topology and determine unicast routes between nodes within the network. This paper presents a comprehensive summarization and a comparative study of newly proposed Dynamic MANET On-demand (DYMO) protocol for MANET and simulation analysis of existing protocols AODV, DSR and DSDV. The comparison is done among these protocols under varying number of nodes over TCP traffic as well as CBR traffic which are randomly generated with CMU generators and having all nodes mobile. Comparative study shows that DYMO is a good choice than other three protocols i.e. AODV, DSR and DSDV if all nodes are mobile and wireless multihop over TCP & CBR traffic generated by CMU’s generator.
