A new protocol system and method is described that utilizes a Schedule Information Vector (SIV) protocol for saving power in wireless local area networks. The protocol includes an access point, one or more stations, and an SIV frame including an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. The access point originates and transmits the SIV frame protocol of the scheduled wake-up time to the stations. The SIV frame protocol of the wireless network is further operable to dynamically adjust the scheduled wake-up times of the stations, a sequence of the wake-up times, a periodic wake-up time, a plurality of wake-up times, and a duration of the wake-up times of the stations. These adjustments may be made based on network traffic, traffic buffering times, data priorities, data length, and data rates.
