A power saving scheme for delivering non-real-time data in IEEE 802.16m

Abstract

How to save power in wireless networks is a crucial problem because the official power saving scheme in IEEE 802.16m does not work efficiently. In this paper, we propose a power saving scheme for delivering non-real-time data. According to behaviors of a client in communication, our power saving scheme can dynamically adjust the sleep time of a client to avoid waking up the client and consuming its power. We use simulations to prove that a client can save more power with our power saving scheme than with the official power saving scheme in IEEE 802.16m.
