4] where ri is the physical rate of the link i in a path composed of n links. The lower the Ip value, the better the route. 11s standard also defines the Airtime Link metric, which considers the time required for a frame transmission [CAR 11, CAM 08a]. 40 Advanced Routing Protocols for Wireless Networks Similar to ETT, it also takes into account the transmission rate and the delivery probability of a frame. Unlike the previous metrics, however, it accounts for the overhead posed by the channel access and the protocol implementation.

Therefore, intermediate nodes can reply to the RREQ only if they have a route to the destination whose corresponding destination sequence number is greater than or equal to the sequence number of the RREQ, which means a “fresher” route. When intermediate nodes forward RREQs, they record in their route tables the address of the neighbor from which the first copy of the RREQ packet is received, thereby establishing a reverse path. Moreover, a route timer is used and the route entry is removed when the timer expires.

ETX is the expected number of transmissions a node needs to successfully transmit a packet to a neighbor. Hence, ETX improves the routing performance by considering the amount of packet losses each link can introduce in an end-to-end route. To compute ETX, routers periodically broadcast probes containing the number of probes received from each neighbor in the last time interval. The number of received probes is calculated at the last interval in a sliding-window fashion. On receiving this feedback, routers are able to estimate the loss rate on the links to and from each neighbor.
