Prediction
Algorithm
lBasic Idea:
uPredict the link breakage time (prediction
algorithm)
uRebuild a route before link breaks (pro-active route
maintenance)
uInvalidate cached routes before they become stale
lPrediction Algorithm
uMonitor unicast packets from neighboring nodes
uUsing signal power strength to predict the link breakage
