Routing protocols often require bi-directional link qualities to compute the routes. Nodes can estimate the quality of the in-bound link from a neighbor by estimating the ratio of successfully received -messages and the total transmitted messages. LEEP appends in-bound +messages to the total transmitted messages. LEEP appends in-bound packet reception rate (PRR) estimates to packets. Other nodes hearing these packets can combine the in-bound PRR values with their own in-bound values to compute bi-directional link quality.

In a node pair (A,B), with B as the node of reference, in-bound link quality is a value in the range of 0 to 255 that describes the quality of the link from A to B estimated by B as the ratio of successfully -received and all packets transmitted by A. Thus, in-bound link quality +received to all packets transmitted by A. Thus, in-bound link quality is the empirical probability that a packet will be successfully received on a given link. A value of 255 represents a probability of 1 and a value of 0 represents a probability of 0 of successfully
