Abstract
A system and method for characterizing the quality of a link, in particular, a bi-directional link, between nodes in a wireless communication network, such as a wireless ad-hoc peer-to-peer network, with minimum network overhead. The system and method determine the quality of link between two nodes by taking into consideration the view from both the nodes, and factors such as signal strength, signal-to-noise ratio or any statistic collected at the physical layer that is deemed representative of the quality of a link. The link quality can also be adjusted using a weighting factor.
