ENERGY SAVING METHOD FOR WIRELESS NETWORKS

摘要

An energy saving method in a mobile network for minimizing the consumption power of each node is provided to minimize the activation period in a normal time, save poser and minimize the amount of power consumption by lengthening a transmission activating period. A source node receives WN(Wakeup Notification) from a target node(S702). The source node determines whether the activating period is sufficient for data transmission(S703). If the activation period is sufficient in data transmission, the source node transmits data frame within the activation period(S704). If the activation period is not sufficient, the source node requests the activation period extension(S705). The source node determines EREP(Extension REPly) reception according to the activation period extension(S706).
