  • Patent number: 8125964
    Abstract: A hybrid mobile ad-hoc network and a method of operating the same, including a mobile network node and a plurality of static network nodes randomly distributed over a coverage area with a predetermined density. The static network nodes form a static infrastructure backbone of the hybrid mobile ad-hoc network. Position information of the static network nodes, either through position awareness or triangulation with reference to other static nodes enhances the network function. The method tracks mobile node position with a minimum of overhead because of the fixed infrastructure of static nodes. The infrastructure can self-heal by placing excess static nodes in a hibernating state, and activating those in response to the failure of a nearby static node.
