Abstract

To enhance power efficiency of battery powered wireless access devices, the behaviors of the mobile stations (MS) working in the sleep mode operation in IEEE 802.16e was researched with a method of the Markov chain model. By exploring the relationship among traffic load, power consumption and delay, we present a cross-layer design-based algorithm to tune the initial sleep window according to the randomization traffic of mobile station. Theoretical analysis and the NS2 simulations results show that the proposed algorithm can save more energy of an MS. Meanwhile, the proposed algorithm bounds the delay in the required range.
