Title:
A METHOD TO PROVIDE A MEASURE OF LINK RELIABILITY TO A ROUTING PROTOCOL IN AN AD HOC WIRELESS NETWORK
Document Type and Number:
WIPO Patent Application WO2004109536
Kind Code:
B1
Abstract:
A system and method for locating optimal routes between source and destination nodes in a communications network, in particular, a wireless ad-hoc communications network by employing a link reliability algorithm that estimates the reliability of links between nodes using a prediction mechanism and a variable-weight filter. The prediction can be based on signal strength, signal-to-noise ratio or any statistic collected at the physical layer that is deemed representative of the quality of a link, and the weighting filter adjusts the predicted value based on the traffic conditions (e.g., idle, light traffic, moderate traffic or heavy traffic) being experienced by the nodes whose link quality is being estimated.
