  • Publication number: 20050249185
    Abstract: In a method for directing packets in a radio network, a route of nodes from an origin to a destination is determined according to a routing algorithm. A packet is transmitted along the route. A failure of a first node to forward the packet along the route is detected. The packet is transmitted to the destination from a second node not on the route.

  • Publication number: 20050226169
    Abstract: A method for identifying nodes in a network includes selecting identification parameters for the nodes in the network. At some nodes in the network, identification information is maintained for a plurality of nodes based on messages received from neighboring nodes, and the identification information is monitored for a conflict between two or more nodes.

  • Patent number: 6496871
    Abstract: A distributed software system and method are provided for use with a plurality of potentially heterogeneous computer machines connected as a network. The system may comprise at least one agent comprising a protection domain, wherein the protection domain of the at least one agent resides on at least two of the plurality of computer machines. A plurality of objects is contained within the protection domain of the at least one agent, a first object residing on a first of the at least two computer machines and a second object residing on a second of the at least two computer machines. The objects are selectively movable among the at least two computer machines by a programmer of the system.

  • Patent number: 5745703
    Abstract: The system comprises a collection of address spaces within which potentially many concurrent lightweight perceptible threads may execute. The address space is uniformly distributed among different nodes in a network of heterogeneous machines. Address spaces are first-class and may be generated dynamically. Threads within an address space may communicate with one another via shared memory; communication between address spaces takes place using explicit message-passing.
