1. A method for improving performance and/or energy utilization in a WLAN system, comprising:

  • a) inducing fluctuations in signal strength transmitted from an access point to stations within a transmission range of the access point; and

    b) exploiting the induced fluctuations using a distributed scheduling algorithm to make the stations channel aware and opportunistic, said distributed scheduling algorithm including that said stations are induced to wait to transmit packets until the induced fluctuations in signal strength transmitted from the access point cause said stations to have a certain link quality.
