We mathematically analyze a sleep mode operation proposed by Samsung for IEEE 802.16 m. The sleep mode operation for downlink traffic is modeled as a 2-dimensional Markov chain. We obtain the power consumption of a mobile station. We show that the power consumption of a mobile station decreases as the sleep cycle increases and the analytical results also match with the simulation results very well.
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 named ??sleep mode?? for conserving the power of the mobile stations. According to the operating mechanism of the sleep mode for...
