摘要： The present invention provides a method and apparatus for extending a zone routing protocol. The invention is configured to provide a robust scalable framework for routing data in wireless ad-hoc networks when unidirectional links 210 are present. When the reverse path from a destination node (the tail) of a unidirectional link 210 to the originating node (the head) of the link is beyond a designated length, the invention is configured to revert to an on-demand search mechanism. The on-demand search mechanism recursively attempts to build a path to the destination 206 by recognizing nodes that have a route to the destination.

摘要： A network node computes a fair share data rate for the sharing of a shared communication channel in a local area network. The network node determines the required information for computing the fair share by snooping the network, by receiving the required information from other network nodes, or a combination of the two techniques. Alternatively, instead of computing the fair share data rate, the network node may receive the fair share data rate which was computed by another network node. The fair share data rate is enforced by the network node in a network protocol stack layer above the media access control layer. In one embodiment, the network protocol stack layer above the media access control layer is the link layer.
