Abstract
The IEEE 802.16e-2005 is designed to support high bandwidth for the wireless metropolitan area network. However, the link quality is likely to degrade drastically due to the unstable wireless links, bringing ordeals to the real-time applications. Therefore, a feasible bandwidth allocation algorithm is required to utilize the precious bandwidth and to provide service differentiation. This article presents the general background of allocation schemes and introduces a Two-Phase Proportionating (TPP) algorithm to tackle the above challenges. The first phase dynamically determines the subframe sizes while the second phase further differentiates service classes and prevents from bandwidth waste. Performance comparison with other algorithms confirms that TPP achieves the highest bandwidth utilization and the most appropriate differentiation.
