Link Capacity Estimation in QOLSR

Capacity-constrained routing, i.e. the ability to find paths that offer available bandwidth above a required limit, in wireless ad hoc networks requires a way to measure link capacity (available bandwidth). Because of the open and shared nature of the radio medium, the capacity of a link is generally not independent of the capacities of neighboring links. In the present paper, we describe a method we use in QOLSR [1] to estimate link capacity using localized information.
