dc.description.abstract	The use of mobile computing devices has become more and more common as such de vices have become more and more affordable and powerful. With increase in through put ~peed and decrease in device size, wireless multimedia streaming to battery pow ered mobile devices have become widespread. However, the battery power has not kept up with the advances in technology and has not increased so rapidly. This defi ciency in battery power provides motivation for development of more power efficient multimedia streaming methods and procedures. This research proposes an Adaptive-Buffer Power Save Mechanism (AB-PS:vI) for in creasing the battery life of mobile devices during multimedia streaming. This increase is achieved by controlling how and when data is sent over a wireless LAN. AB-PSM introduces an additional buffer which hides data from the station it is intended for, allowing it to return to sleep and consequently saving power. Data is eventually delivered in one of the stations following attempts to receive it. Tests involving AB PSM have been performed and show good simulation results in terms of significant increases in battery lifetime. The comparison between AB-PSM and the Institute of Electrical and Electronics Engineers (IEEE )802.11 legacy power save mechanism shows important increases in battery lifetime of more than 100%.	en_US
