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...
The power-saving class of type I (PSC I), which is one of the sleep-mode operations specified in the IEEE 802.16 e standard, is designed to reduce power consumption for nonreal-time traffic. However, the inefficiency of the PSC I comes from the configuration of its operation and the utilized mechanism of binary-exponential traffic detection. Based on the concepts of IEEE 802.16 m sleep-mode operation,...
The limitation on the battery lifetime has been a critical issue for the advancement of mobile computing. Different types of power-saving techniques have been proposed in various fields. In order to provide feasible energy-conserving mechanisms for the mobile subscriber stations (MSSs), three power-saving types have been proposed for the IEEE 802.16e broadband wireless networks. However, these power-saving...
The design of an efficient handover technique is considered a crucial topic in the cellular-based wireless networks. Feasible handover process can minimize the performance degradation as the mobile station (MS) is moving between different base stations (BSs). Based on the IEEE 802.16e standard, it is required to provide satisfactory handover performance under a wide-range of MSpsilas moving speeds...
Different types of power-saving techniques have been proposed in various fields to alleviate the limitation on the battery lifetime for the mobile stations (MSs). In order to provide feasible energy-conserving mechanism, three different power-saving types have been introduced in the IEEE 802.16e broadband wireless networks. By means of pre-negotiations, the MS can be absent from the serving base station...
