Method for discovering a mobile host that roams across wireless networks, each wireless network comprising a mobile router and the mobile routers being coupled to a gateway. The method includes receiving a packet comprising an address of the mobile host within one of the wireless networks; and determining whether the address of the mobile host resolves to be within a subnet of mobile hosts manageable by the mobile router of the one wireless network. When both the address of the mobile host resolve to be within the subnet of mobile hosts manageable by the mobile router of the one wireless network, the method further includes adding the address of the mobile host to a table of registered mobile hosts for the mobile router of the one wireless network, the packet comprising a dynamic host configuration protocol (DHCP) lease request for the mobile host.

Multi-network seamless roaming mobile router with auto-discovery and migration of downstream devices on the mobile network

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.
