Reducing Control Packets through Modified AODV with TCP Tahoe in MANET

Syed Masood M, Sheik Abdul Khader P

Abstract :

The aim of this paper is to reduce the routing overhead by combining both network layer and transport layer operating in Mobile Ad hoc Network (MANET). A MANET is an autonomous system of mobile routers connected by wireless links. The routers are free to move and organize themselves arbitrarily and therefore wireless network topology may change rapidly and unpredictably. The traditional Ad hoc On-demand Distance Vector (AODV) routing protocol floods the RouteRequest packet in the network when a route is not available for the desired destination. The goal of the proposed Probabilistic Scheme is based on AODV (PSAODV). This modified protocol oadcasts the RouteRequest packet by setting the reoadcast probability based on the number of neighbors around each node and the proper TCP variant is used to deliver the packets from end to end over MANET. TCP Tahoe variant is better at congestion avoidance and therefore use network resources efficiently. The simulation studies were carried out with different parameters, such as number of nodes, node mobility speed and various source types were compared with other existing routing protocol in terms of packet delivery ratio, end-to-end delay and routing overhead. The simulation results show that the modified protocol performs better than the existing AODV.
