Interconnection of wired Internet and wireless mobile ad hoc networks, called Integrated Internet-MANET enables communication between wired and wireless peers. Many strategies exist which provide Internet connectivity to the mobile ad hoc network nodes through one or more Internet gateways. Mobile nodes need to be registered with an Internet gateway in order to communicate across the Internet. A key issue in such strategies is to distribute the Internet bound traffic across the Internet gateways evenly. The problem of Internet gateway load balancing has been addressed by researchers in interesting ways. In this paper, we present a review of the gateway load balancing solutions under common parameters. In the second part of the paper, a new gateway load balancing strategy based on a load balanced routing protocol called Modified AODV is proposed and is simulated using the ns-2 simulator.
