摘要
IEEE 802.16e is the latest broadband wireless access standard designed to support mobility. In mobile networks, how to control energy consumption is one of the most important issues for the battery-powered mobile stations. The standard proposes an energy saving mechanism that named "sleep-mode" for conserving the power of the mobile stations. Considering both downlink traffics and uplink traffics, a queueing model of two servers sharing vacations with close down time and multiple inhomogeneous vacations is built in this paper. By employing two-dimension embedded Markov chain method, we get the performance measures of the energy saving ratio, the system handover ratio, and the average data frame delay time for the sleep-mode in the IEEE 802.16e. Finally, numerical results are given to demonstrate the dependency relationships between the system performance measures and the system parameters.
