A Novel Energy Saving Algorithm with Frame Response Delay Constraint in IEEE 802.16e

چکیده
Sleep-mode operation of a Mobile Subscriber Station (MSS) in IEEE 802.16e effectively saves energy consumption; however, it induces frame response delay. In this letter, we propose an algorithm to quickly find the optimal value of the final sleep interval in sleep-mode in order to minimize energy consumption with respect to a given frame response delay constraint. The validations of our proposed algorithm through analytical results and simulation results suggest that our algorithm provide a potential guidance to energy saving. key words: IEEE 802.16e, sleep-mode, energy saving

A Dynamic Sleep Interval Decision Scheme for Power-Saving with Minimum Delay in IEEE 802.16e Mobile WiMAX
We observe that the state-of-the-art power-saving mechanisms (PSM) for IEEE 802.16e is neither optimal in terms of delay nor in terms of energy consumption. We propose a new PSM which achieves the optimality in terms of the average buffering delay without increasing energy consumption. In order to do so, we derive a formula which relates the average buffering delay to sleep intervals. Simulatio...
