Link duration based routing protocol for multihop ad hoc networks
First Claim
1. A method for selecting a route for transmitting data packets amongst nodes in an ad hoc network, comprising:
- initiating a route discovery procedure that generates a plurality of candidate transmission paths between a source node and a destination node;
determining a metric which is indicative of link stability between nodes in the network; and
selecting a transmission path from amongst the plurality of candidate paths using the metric for nodes associated with each candidate path.

Abstract
A method is provided for selecting a route for transmitting data packets amongst nodes in an ad hoc network. The method includes determining a metric which is indicative of link stability between the nodes in the network; initiating a route discovery procedure that generates a plurality of candidate transmission paths between a source node and a destination node; and selecting a transmission path from amongst the plurality of candidate paths using the metric for nodes associated with each candidate path. The metric may be further defined as link duration (i.e., an amount of time the node maintains a link with neighboring nodes link duration).

9. A method for selecting a route for transmitting data packets in a mobile ad-hoc network, comprising:
-
determining link duration between nodes in the network prior to route discovery, where link duration is an amount of time a given node maintains a link with neighboring nodes;
initiating a route discovery procedure which results in a plurality of candidate transmission paths between a source node and a destination node; and
selecting a transmission path from amongst the plurality of candidate paths based in part on the link duration of nodes associated with each candidate path. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A node in a mobile ad-hoc network, comprising:
-
a link duration module residing in a network layer and operable determine link duration for the node, where link duration is an amount of time the node maintains a link with neighboring nodes; and
a routing metric module adapted to receive route request packets and operable to compute a routing metric based on the link duration. - View Dependent Claims (18, 19, 20, 21)
