In this paper, we analytically evaluate the sleep mode operation of the IEEE 802.16e, defined for the power saving. In the sleep mode, an mobile subscribe station (MSS) sleeps for a sleep window and wakes up at the end of the sleep window in order to check pending download packet(s) destined to itself. If there is no such a packet, the MSS doubles the sleep window up to the maximum value and sleeps again. For a quantitative analysis, we model the sleep mode operation as a semi-Markov chain. Then, the average packet delay and average power consumption are analytically derived. Based on the performance analysis, we discuss selecting the proper set of operational parameter values for a given traffic arrival pattern
