Executive Summary

Wi-Fi (Wireless Fidelity) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves) over a computer network, including high-speed Internet connections. The Wi-Fi consists of Access Points (AP) and several clients. Large number of clients makes use of single AP's. This will lead to traffic, which in turn lead to loss of energy and battery lifetime in Mobile Devices. One of the early protocols used is Power Save Mode (PSM) in which the client wakes up periodically. The solution is that, there contains a technology called SleepWell, a system that achieves energy efficiency by evading network contention. That is, the client will give the request to the AP and battery of the mobile devices will be in sleep mode.
