Performance Analysis and Enhancement of Distance Based Routing Protocol in MANET

A mobile ad hoc network (MANET) is a collection of wireless mobile nodes communicating with each other using multi-hop wireless networks. One of the main challenges of MANET is the design of robust routing algorithms that adapt to the frequent and randomly changing network topology. This feature leads to frequent path failures and route reconstructions, which causes an increase in the routing control overhead. A variety of routing protocols have been proposed and several of them have been extensively simulated or implemented as well. Existing distance based routing protocols like Ad-hoc On-demand Multipath Distance Vector (AOMDV) routing protocol, which is a multipath routing protocol, Destination sequence distance vector (DSDV) routing protocol, Distance Routing Effect Algorithm For Mobility (DREAM), Secure Efficient Distance Vector Routing For Mobile Wireless Ad Hoc Networks (SEAD), and Polarized Gossip Protocol (PGP) are analyzed and concluded that PGP performs well compared to other protocol mentioned above. In proposed work the position-based routing features combined into on-demand routing protocols and proposes a distance based routing protocol (EDRP) in the absence of positioning service to improve the route discovery.
