Amelioration of load balanced gateway selection protocol in integrated Internet-MANET

Internetworking of different types of networks is envisaged as one of the primary objectives of the future 5G networks. One such heterogeneous internetworking architecture is the interconnection of Internet and MANET, called Integrated Internet-MANET. Multiprotocol gateways are used to achieve this interconnection. Some of the most important issues in realizing Integrated Internet-MANET are efficient gateway discovery, mobile node registration and gateway load balancing. In this paper, an improvement is proposed to an existing solution which addresses the issues of efficient gateway discovery and load balancing. The proposed approach uses a genetic algorithm to optimize the gateway load balancing protocol. The proposed protocol has been simulated using network simulation tool ns-2. Based on the simulation results, it is observed that the proposed protocol not only delivers better performance than the existing protocol, but is also optimized using the proposed genetic algorithm.
