Dynamic Gateway Load Balancing in Integrated Internet-MANET

Mobile Ad hoc Network (MANET) is a network of mobile devices capable of configuring itself. MANETs does not have any fixed topology. MANETs are combined with internet forming a hybrid network to widen the coverage and to access the global services. The mobile Nodes in MANET can be connected to the internet through gateways. There are 2 types of gateways. Namely Static gateways, Dynamic gateways. To connect mobile nodes with internet these nodes must find and register with the gateways using gateway discovery mechanism. In this paper we are proposing the concept of Dynamic gateways. One of the issues in integrated internet-MANET is congestion. To address this issue we proposed a load balancing algorithm. Our algorithm reduces congestion in the network by balancing the load among mobile nodes and gateways as well. The parameters used for the performance analysis of our algorithm are Packet delivery ratio, throughput and routing overhead.
