Reduced State

IEEE 802.16e is extensively used these days for both data and voice communications as it makes available high-speed wireless access. However, in view of the fact that mobile subscriber stations are powered by a limited capacity battery, power saving mechanism is necessary to improve network performance. In this article, the authors introduce a load based sleep scheduling mechanism with reduced state transitions for IEEE 802.16e Networks. The mechanism encompasses two phases, load-based sleep scheduling and a reduced state transition (RST) algorithm. Considering network load information, the Base Station (BS) assigns a sleep window size for each mobile subscriber station (MS). The proposed RST algorithm reduces the number of state transitions between sleep and active mode by watchfully combining any two adjacent active bands. Further, the technique considers network load and delay as QoS metrics. Through simulation results, the authors prove the proficiency of their mechanism.

This work proposes two enhanced multiple mobile subscriber stations (MSSs) power-saving scheduling methods for IEEE802.16e broadband wireless networks. The proposed methods are designed for the Unsolicited Grant Service (UGS) of IEEE802.16e. To reduce the active periods of all power-saving MSSs, the base station (BS) allocates each MSS fewest possible transmission frames to retrieve its data from the BS. The BS interlaces the active periods of each MSS to increase the amount of scheduled MSSs and splits the overflowing transmission frames to maximize the bandwidth utilization. Simulation results reveal that interlacing the active periods of MSSs can increase the number of scheduled MSSs to more than four times of that in the Direct scheduling method. The bandwidth utilization can thus be improved by 60%–70%. Splitting the overflowing transmission frames can improve bandwidth utilization by more than 10% over that achieved using the method of interlacing active periods, with a sacrifice of only 1% of the sleep periods in the interlacing active period method.
