<p><P>PROBLEM TO BE SOLVED: To provide a system and method for link quality routing using a weighted cumulative expected transmission time path metric. <P>SOLUTION: A system for routing in a multi-hop ad hoc network, and a method for measuring the link quality of a route in the network, include assignment of a weight to a link in accordance with an expected transmission time of a packet over the link, and a combining of individual link weights for a route into a path metric. The path metric accounts for interference among links that uses a shared channel. In the calculation of the path metric, the expected transmission times of links that interfere with one another are added, while the expected transmission times for non-interfering links are considered separately. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
