  • Patent number: 7936732
    Abstract: In one embodiment, a method includes determining, at a local node in a network of multiple nodes, a first neighbor node of one or more neighbor nodes with which the local node is in direct communication based on a first number of nodes with which the first neighbor node is in direct communication. The first neighbor node is selected as an aggregation node for information about the local node. The aggregation node outputs data that is a combination of data received from multiple different nodes. The method allows wireless routers in mobile ad hoc networks to automatically determine their own aggregation nodes for routing information and thus automatically enables routing protocols to scale for many thousands of mobile wireless nodes.

  • Publication number: 20090161542
    Abstract: The present disclosure provides a technique for propagating resource availability information in a network. The technique generally includes storing resource availability information indicating end to end bandwidth availability on multiple paths between the apparatus and a destination in a network and calculating the end to end bandwidth availability based on resource capacity information received from network nodes along the multiple paths.
