DATA-PATH DYNAMIC LINK MAINTENANCE IN MOBILE AD HOC NETWORKS
First Claim
1. A mobile ad hoc network comprising:
- a plurality of mobile nodes comprising a source node, a destination node, and a plurality of intermediate nodes therebetween configured to establish a main communications path and at least one alternative communication path thereby defining a multipath communication pathway between said source node and said destination node;
at least one of said intermediate nodes comprising a controller and a wireless communications device cooperating therewith to monitor link quality to neighboring nodes, and to reconfigure the main communication path to the at least one alternative communication path based upon the monitored link quality.

Abstract
The method and mobile ad hoc network include the use of a plurality of mobile nodes. A main communication path is established from a source node through intermediate nodes to a destination node. Alternative communication paths are established among intermediate nodes defined as standby nodes to define a multipath communication pathway from the source node to the destination node. The nodes include a controller and a wireless communications device cooperating therewith. Link quality is monitored by at least one intermediate node to neighboring nodes in the multipath communication pathway, and the main communication path is reconfigured within the multipath communication pathway to at least one of the alternative communication paths based upon monitored link quality.
