IEEE 802.16 technology has emerged as a competitive alternative to wireline broadband access solution. IEEE 802.16 can provide quality of service (QoS) guarantees for heterogeneous classes of traffic with different QoS requirements. The standard, however, leaves open the resource management and scheduling issues, which are crucial components to guarantee QoS performance. The main objective of this...
In this paper, we propose a radio resource scheduling algorithm for a scheduler in IEEE 802.16 orthogonal frequency division multiple access (OFDMA) specification. The scheduler dynamically allocates slots considering wireless channel conditions of subscriber stations to improve radio resource utilization efficiency. The results show that with the proposed algorithm, smaller radio resources are used...
The IEEE 802.16 broadband wireless access (BWA) system offers a cost-effective solution to the last-mile wireless connection problem. To provide the necessary QoS guarantees to the multimedia traffic in BWA systems while utilizing the resources as efficiently as possible, optimal scheduling mechanisms and resource allocation strategies are needed. In this paper, we model the resource request and distribution...
