چکیده

Femtocell technique has become a radical approach to improve network capacity and coverage. To efficiently reduce interference between femto BS and other BSs, low duty operation mode (LDM) is deemed as a good method to mitigate the interference. In this work, we develop a mechanism that incorporates the power saving mechanism in both femto BS (LDM mode) and MSs (sleep mode). To correspond to the current IEEE 802.16m system architecture, we build a practical system model and analyze the performance of the proposed modification. The simulation shows that with simple sleep-cycle operation, our mechanism can achieve both a high sleep ratio and an acceptable low delay without generating more control overhead than original system requirement. With the above characteristics, our mechanism provides a solid basis to create a green communication system.

Energy Efficient Networking with IEEE 802.16m Femtocell Low Duty Mode

Femtocell technology has become a radical approach to improve network capacity and coverage. Because femtocells can use the same frequency bands as the cellular network, the cochannel interference is a critical issue in femto networks. To efficiently reduce interference between femto BS and other BSs, low duty mode (LDM) operation has been developed. In this work, we construct a mechanism integ...

Performance Improvement of IEEE 802.15.4 Beacon-Enabled WPAN with Superframe Adaptation Via Traffic Indication

The IEEE 802.15.4 standard provides the widely accepted solution for low-cost and low-power wireless communications. Despite its design support for low duty-cycle operation, the fixed superframe size in Beacon-enabled mode limits its capabilities due to two contrasting goals; energy efficiency and higher data throughput. In this paper, we propose an enhancement of IEEE 802.15.4 Beacon-enabled m...
