Abstract

The mobile ad hoc network includes a plurality of wireless mobile nodes and a plurality of wireless communication links connecting the nodes together. A method for managing and controlling the discovery and maintenance of routes in the network includes transmitting beacon signals from each mobile node, determining a node or group condition at each mobile node, and varying the beacon signals based upon the determined node / group condition. Route tables are bulit and updated at each mobile node with a first one of proactive and reactive route discovery processes to define routes in the network. The beacon signals are received and node / group condition information is stored at each node. Route stability over time is predicted based upon the node / group condition information, and when predicted route stability reaches a first transition parameter the method switches to a second one of the proactive and reactive route discovery processes.

Description

Background of the invention [0001] Wireless networking has experienced rapid development over the past decade. One of the fastest growing areas is the mobile ad hoc (ad hoc) network. Physically, a mobile ad hoc network consists of a plurality of geographically distributed, potentially mobile nodes wirelessly connected by one or more radio frequency channels. The most distinctive feature of mobile ad hoc networks is the lack of any fixed architecture compared to other types of networks such as cellular or satellite networks. Networks are formed only by mobile nodes, and when nodes send to or receive from other nodes, create the network as you like. Networks are generally independent of specific nodes and adjust dynamically as some nodes join or others leave the network. [0002] In adverse environments where fixed communication infrastructure is unreliable or unavailable, such as in a battlefield or in natural disaster areas hit by earthquakes or hurricanes, an ad hoc networ...
