| Description |
This article provides an overview of mechanisms used for power saving in the upcoming standards for wireless lans: ieee 802.11 and etsi res 10 hiperlan. Power saving on the mac level is addressed by these standards in a quite different way. We outline the main features of the mechanisms in both standards in terms of power saving. In addition we present simulation studies of the power-saving mechanism in ad hoc configurations of ieee 802.11 networks, which demonstrate the optimization potential and some performance trade-offs quantitatively
