  • Method for improved handover in multiple interface application
    Patent number: 8634377
    Abstract: A method is provided for establishing a backup interface among multiple interfaces serving a mobile node, for a handover that is undetectable in advance. The invention methodology operates to cause a Foreign Agent associated with the multiple interfaces to keep a binding record of each of the multiple interfaces for which the mobile node has successfully completed the registration process. A novel Mobile IP extension is also added to facilitate the backup FA binding of the invention methodology.

  • System and domain name server for ad-hoc networks
    Patent number: 8621086
    Abstract: The present invention relates to a system and domain name server for ad-hoc networks. Embodiments of the present invention provide a mobile router providing connectivity to end users in an ad-hoc network. The mobile router includes a domain name server (DNS server) configured as a master DNS server at a node associated with the mobile router for end users that enter the ad-hoc network through the node. The DNS server stores records of name-address translations for the end users. A management structure of the DNS server at the node includes a domain name for the node coinciding with a domain name at a lowest level in a hierarchy of a domain name system.
