According to the operation mechanism of the sleep mode for the power saving type Ⅰ in IEEE 802.16e, this paper builds a multiple vacation queueing model with exponential variational vacation length. The queueing parameters such as queueing length with steady state, the average waiting time and the average busy cycle are given. The formula of the energy saving ratio and the performance measure of average response time are derived. Dependency relationship between the system performance measures and the size of initial sleep window are obtained through numerical examples.
