Claims
- 1. A method for locating optimal routes between source and destination nodes in an ad-hoc multi-hopping peer-to-peer wireless communications network, the method comprising:
estimating reliability of links between nodes in the network using a prediction mechanism and a variable-weight filter to identify an optimal route including some of the nodes between the source and destination nodes, such that the variable-weight filter adjusts the predicted value based on the traffic conditions being experienced by the nodes whose link qualities are being estimated; and selecting a route between the source and destination nodes comprising the nodes having the most preferable link qualities as determined in the estimating step.
- 2. A method as claimed in claim 1, wherein:
the predicted value is based on at least one of signal strength and signal-to-noise ratio.
- 3. A method as claimed in claim 3, wherein:
the traffic conditions include idle, light traffic, moderate traffic or heavy traffic.
- 4. A method as claimed in claim 1, wherein:
the source and destination nodes are mobile nodes.
