Patent ID: 7420954

Claim:
A method for information dissemination in a wireless mobile ad hoc network comprising: receiving a request to communicate information from a source node to a destination; identifying each neighbor node of the source node in the ad hoc network; invoking a proactive border node broadcast protocol at the source node when the destination is a neighbor node and wherein the number of hops to the destination is less than a predetermined number of hops; invoking an on-demand border node broadcast protocol at the source node when the number of hops from the source node to the destination exceeds the predetermined number; and communicating the information from the source node based on the invoked broadcast protocol by: selecting at least one neighbor node as a border node based on a geographic location of the neighbor node and geometric criteria by determining at least one neighbor node having both a maximum distance from the source node and a minimum distance to a one of the compass point directions North, South East and West; and broadcasting the information from the source node, wherein the broadcast information identifies the selected at least one border node and a communication destination.
