Weighted load balanced adaptive gateway discovery in integrated internet MANET

Abstract

An Integrated Internet MANET (IIM) is a heterogeneous network which is an interconnection of the wired Internet and the wireless MANET. Two of the issues which arise in Integrated Internet-MANET are gateway load balancing and efficient gateway discovery. These two issues have been addressed separately in the literature. In this paper, a mechanism is presented which incorporates gateway load balancing and adaptive gateway discovery together. The proposed mechanism uses the Maximal Source Coverage algorithm for dynamically adjusting the proactive range of the IIM while using the WLB-AODV routing protocol for gateway load balanced routing of packets in the MANET. Simulation results using ns-2 network simulator show that the proposed protocol gives better performance in terms of packet delivery ratio and end to end delay than the existing approach.
