Performance analysis and comparison of sleep mode operation for IEEE 802.16m advanced broadband wireless networks

The IEEE 802.16m standard is developed to support advanced services with high data rate and high mobility for the next generation broadband wireless access networks. A novel sleep mode operation is specified in the standard to conserve the energy of mobile devices. In this paper, a concise analytical model for the sleep mode operation of the IEEE 802.16m is proposed. The effects of both downlink and uplink traffic are properly considered in the proposed model. The power-saving efficiency and mean waiting time are utilized as the metrics for performance analysis. Simulations are performed in order to validate the effectiveness of the proposed system model. Moreover, the performance comparisons between the IEEE 802.16m and IEEE 802.16e are also conducted in the simulations.
