Abstract
A mobile router offers seamless roaming services to one or more locally connected mobile hosts over one or more simultaneously connected networks. The mobile router, as well as its local area network, roams across different subnets on similar networks, across networks that are dissimilar, or across a simultaneous combination of both. Simultaneous support is provided for mobile hosts configured for static IP addressing and mobile hosts configured for dynamic IP addressing. Seamless support is provided for mobile hosts that dynamically migrate from one mobile router to another mobile router, while avoiding the need for configuration settings on the mobile router that are associated with individual mobile hosts and avoiding the need for mobility support software on the mobile hosts themselves.
