In the area of wireless mobile communication, minimizing energy consumption as well as maximizing data throughput in Medium Access Control (MAC) layer is a very important research issue. The Distributed Coordination Function (DCF) of IEEE 802.11 provides the Power Saving Mechanism (PSM) that allows nodes to remain silent in 'Doze mode' for reducing energy consumption. However, IEEE 802.11 PSM is known to cause unnecessary energy consumption due to the problems of an overhearing, a back-off time delay and possible packet collisions. To overcome these problems, the paper presents a new MAC protocol called 'Slotted-PSM' for IEEE 802.11 WLANs.
