A novel solution for global connectivity in MANET

Providing an effective Internet access solution for mobile nodes in a mobile ad hoc network (MANET) is a challenging task because of the dynamic nature of the ad hoc network. This dynamic nature leads to difficulties in addressing, routing and data delivery. In this paper, we proposed a new solution for Internet access by using multiple access routers (ARs) simultaneously. This brings a lot of benefits such as effective soft-handoff, throughput improvement, load balancing between ARs, etc. In addition, hierarchical mobile IP (HMIP) is incorporated into our solution to speed up handoff, and to maintain the Internet connection using the regional care of address (RCoA). The simulation results for both proactive and reactive ad hoc routing protocols with two ARs show an improvement of network throughput, especially in the small sized network.
