Enhanced route discovery in Mobile Adhoc Networks

Mobile Adhoc Network (MANET) is a collection of wireless mobile nodes. In MANET nodes are self-motivated topologies can arbitrarily change their geographic locations. MANET consists of wireless links with considerable bandwidth. Packet delivery needs routing protocol to transmit a packet from source to destination. In such a network, nodes move, the established paths may break and the routing protocols must dynamically search for other feasible routes. Numerous protocols have been developed for mobile ad hoc mobile networks. Such protocols must deal with the typical limitations of these networks, which include high power consumption, low bandwidth and high error rates. These MANETs routing protocols are categorized in to Proactive Routing Protocols (PRP), Reactive Routing Protocols (RRP) and Hybrid Routing Protocols (HRP). This paper presents routing in wireless mobile ad-hoc networks using Destination Sequenced Distance Vector (DSDV) and Ad-hoc on demand Distance Vector (AODV) protocols. The performance of bandwidth, throughput and packet loss of DSDV and AODV has been modeled under various network configurations and mobility conditions. These mechanics can lead to significant performance differentials. The results are justified through NS-2 simulation.
