ROUTING PROTOCOL SELECTION BASED UPON MOTION-INFERRED LINK METRIC IN MOBILE AD-HOC NETWORKS
First Claim
1. A method for managing and controlling the discovery and maintenance of routes in a mobile ad hoc network (MANET) comprising a plurality of wireless mobile nodes, the method comprising:
- determining, at at least one wireless mobile node, additions and drop outs over time of neighboring nodes in communication with the at least one wireless mobile node;
generating a motion-inferred link metric based upon the additions and drop outs over time;
selecting a routing protocol from a plurality of possible routing protocols based upon the motion-inferred link metric; and
discovering routes, with the selected routing protocol, from the at least one wireless mobile node to other wireless mobile nodes within the MANET.

Abstract
Dynamic routing protocol selection capability may be provided within a MANET without the cost of position and/or motion sensing or calculating hardware. The method manages and controls the discovery and maintenance of routes in the MANET, and may include determining additions and drop outs over time of neighboring nodes in communication with a wireless mobile node, and generating a motion-inferred link metric based upon the additions and drop outs over time. A routing protocol may be selected from a plurality of possible routing protocols based upon the motion-inferred link metric, and routes may be discovered with the selected routing protocol to other wireless mobile nodes within the network.

9. A method for managing and controlling the discovery and maintenance of routes in a mobile ad hoc network (MANET) comprising a plurality of wireless mobile nodes, the network operating in accordance with a multilayer protocol hierarchy including a network layer and a data link layer at each wireless mobile node, the method comprising:
-
at the data link layer of at least one wireless mobile node, monitoring additions and drop outs over time of neighboring nodes in communication with the at least one wireless mobile node; at the network layer of the at least one mobile node, calculating a rate of change of neighboring nodes based upon the monitoring; at the network layer of the at least one mobile node, discovering routes, with a first routing protocol, from the at least one wireless mobile node to other wireless mobile nodes within the MANET; and at the network layer of the at least one mobile node, selecting a second routing protocol, different from the first routing protocol, based upon the calculated rate of change. - View Dependent Claims (10, 11, 12)
