  • Patent number: 6845091
    Abstract: Described is an internetworking system having various mobile ad hoc extensions to the Internet that are particularly suited to the dynamic environment of mobile ad hoc networks. The internetworking system includes any combination of a link-state routing protocol for disseminating topology and link-state information over a multi-hop network comprised of nodes, a neighbor discovery protocol that can detect the appearance and disappearance of new neighbor nodes, an address format that facilitates deployment of IPv6 nodes in a predominantly IPv4 network infrastructure, a queuing mechanism that can update information upon resuming interrupted communications between nodes, and dynamic network measurement techniques for adaptively using wireless bandwidth when establishing and maintaining connections between nodes and a server.
    Type: Grant

  • Patent number: 6263360
    Abstract: Methods and apparatus for maintaining updated information on client/server object-oriented computing systems are disclosed. In accordance with one aspect of the present invention, a client/server object-based computing system includes a server which has a server object list that is arranged to include objects that are to be updated. The system also includes a client which has a client object list that contains an object in which the client has interest. The objects that are to be updated include the object in which the client has interest, and the server is arranged to send a message to the client that indicates that the object in which the client has interested should be updated on the client. In one embodiment, the client and the server are in communication over a low-bandwidth link.
