Signal Stability Based Adaptive Routing (SSA) [Dube97] Similar to DSR A node X re-broadcasts a Route Request received from Y only if the (X,Y) link is deemed to have a strong signal stability Signal stability is evaluated as a moving average of the signal strength of packets received on the link in recent past An alternative approach would be to assign a cost as a function of signal stability 192
Associativity-Based Routing (ABR) [Toh97] Only links that have been stable for some minimum duration are utilized motivation: If a link has been stable beyond some minimum threshold, it is likely to be stable for a longer interval. If it has not been stable longer than the threshold, then it may soon break (could be a transient link) Association stability determined for each link measures duration for which the link has been stable Prefer paths with high aggregate association stability 193
