- Abstract
- Since Internet gateways route all packets to and from the Internet, they are likely to become the traffic bottleneck between Ad Hoc networks and the Internet. Although multiple Internet gateways can be used to distribute the traffic load, the possibility of congestion in some Internet gateway still exists in case of uneven traffic distribution if the default Internet gateway selection scheme based on hop-distance is used. In this paper, we propose a load-based Internet gateway selection scheme to distribute the traffic load over multiple Internet gateways. The proposed Internet gateway selection scheme is applied during the on-demand route discovery and the Mobile IP agent discovery procedure. To allow mobile nodes to select less congested Internet gateway as their default Internet gateway, the proxy route reply and solicited agent advertisement messages are adaptively delayed according to Internet gateway's load.
