摘要
In one embodiment, an expected transmission count (ETX) link metric is computed for a link between a transmitter and a receiver in a communication network, the ETX representative of an expected number of transmissions necessary for a message to be successfully received by the receiver over the link, and a data rate of the link at which the ETX is computed is also determined. From these, an estimated transmission overhead (ETO) link metric for the link may be computed by dividing the ETX by the data rate. In one embodiment, the data rate of the link may be adjusted based on the ETO (e.g., to minimize the ETO). In another embodiment, routes through the communication network may be selected based on ETO values along the route.
