Abstract:	摘要： In this paper, we propose a novel bandwidth allocation algorithm for a two-tier hierarchy in IEEE 802.16 time division duplex mode wireless access networks under symmetric and/or asymmetric uplink and downlink traffic input. We demonstrate the performance of the new bandwidth allocation algorithm in terms of accumulated throughput (cumulative bandwidth) and fairness in both infinite and finite buffer cases compared with others by simulations. The simulation results show that the proposed algorithm not only can provide much better fairness and maintain satisfactory QoS support and high cumulative bandwidth but also in the case of finite buffer depth is less buffer-consuming than the others, meaning that the hardware cost can be reduced by employing the proposed algorithm. 其他題名： Wireless Pers Commun 出版者： Boston: Springer US 出版日期： 2012-12 出處： Wireless personal communications, 2012-12, Vol.67 (3), p.665-688 版權： Springer Science+Business Media, LLC. 2011 識別號： ISSN: 0929-6212 識別號： EISSN: 1572-834X 識別號： DOI: 10.1007/s11277-011-0403-7
