Recently, broadband wireless networks, such as IEEE 802.16 and LTE, receive more and more attention from the researchers. Increasing the energy efficiency of the end clients in these systems is an important research task and the evaluation of the energy efficient mechanisms remains an open problem. In this paper, the authors consider the sleep mode control algorithm of the novel metropolitan area networking standard, known as IEEE 802.16m. Also, they introduce an alternative enhanced algorithm that contains the features described by the previous standard versions. They compare the sleep mode performance under the control of both standard and proposed algorithms for different arrival flow types and QoS restrictions.
