The primary concern of broadband wireless technologies is to provide the end-to-end Quality of Service (QoS) for integrated real-time and non real-time applications. The main focus of the IEEE 802.16d/e MAC layer is to manage the radio recourse in an efficient way. The basic functional blocks of the QoS model are addressed by the standards to support five different types of service classes. However, the detailed admission control, radio resource management and scheduling are left for implementation perspective and many research efforts are on going to assure the QoS for end customers. In this paper we propose a hybrid uplink scheduling algorithm (P+E) for subscriber station (SS), which is the combination of priority and Earliest Due Date (EDD) scheduling methods to maintain QoS and utilize the radio resource allocated by the BS in an efficient manner. Simulation results demonstrate the advantages of the proposed hybrid scheduling algorithm.

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 paper is to provide a better understanding of the missing components to ensure QoS support in IEEE 802.16 fixed broadband wireless networks (BWNs), namely scheduling and connection admission control (CAC) schemes. First, we highlight the key challenges in designing such schemes, for both point-to-multipoint (PMP) and mesh modes. Then, we survey, classify, and compare different scheduling and admission control mechanisms proposed in this work-in-progress area.

“…Delay based algorithm is specifically designed for both real time traffic and non real time traffic, where the delay tolerance is the primary QoS parameter. Earliest Due Date (EDD) is the basic algorithm for scheduler to serve the connection based on the deadline [7,12]. However, this algorithm does not guarantee the throughput for higher priority service viz.UGS.…”

IEEE 802.16 is standardization for a broadband wireless access in network metropolitan area network (MAN). IEEE 802.16 standard (Wi-Max) defines the concrete quality of service (QoS) requirement, a scheduling scheme and efficient packet scheduling scheme which is necessary to achieve the QoS requirement. In this paper, a novel waiting queue based on downlink bandwidth allocation architecture from a number of rtps schedule has been proposed to improve the performance of nrtPS services without any impaction to other services. This paper proposes an efficient QoS scheduling scheme that satisfies both throughput and delay guarantee to various real and non-real applications corresponding to different scheduling schemes for k=1,2,3,4. Simulation results show that proposed scheduling scheme can provide a tight QoS guarantee in terms of delay for all types of traffic as defined in WiMax standards. This process results in maintaining the fairness of allocation and helps to eliminate starvation of lower priority class services. The authors propose a new efficient and generalized scheduling schemes for IEEE 802.16 broadband wireless access system reflecti ng the delay requirements.
