IEEE 802.16 based Worldwide Interoperability for Microwave Access networks (WiMAX) are increasingly being deployed for last hop broadband wireless access. In order to provide the high speed access to information resources broadband technology like WiMAX is needed. In this paper we compared different uplink scheduling algorithms of WiMAX mainly maximum carrier to interference and noise (Max C/I) algorithm...
Earliest Deadline First (EDF) is a delay-optimal scheduling algorithm which is commonly used in real-time applications such as Voice over IP (VoIP) and Video on Demand (VoD) in wired and wireless networks. EDF calculates the deadline of a packet as follows: the latency parameter provided by the subscriber during admission control is added to the arrival time of the packet to form the packet deadline...
The IEEE 802.16 Working Group on Broadband Wireless Access is developing the standard for broadband wireless access networks in Metropolitan Area Network (MAN), also know as WiMAX. One of the features of the 802.16 MAC layer is that it is designed to differentiate service among traffic categories with different multimedia requirements. Based on these assumptions and considering that the standard does...
IEEE 802.16 is a standardisation for a broadband wireless access in metropolitan area networks (MAN). Since the IEEE 802.16 standard defines the concrete quality of service (QoS) requirement, a scheduling scheme is necessary to achieve the QoS requirement. Many scheduling schemes are proposed with the purpose of throughput optimisation and fairness enhancement, however, few scheduling schemes support...
Fourth generation networks will almost invariably adopt OFDMA (orthogonal frequency division multiple access) and MIMO (multiple input-multiple output) technologies, in order to meet high data rate and quality of service (QoS) requirements. The worldwide interoperability for microwave access (WiMAX) MAC Layer, which is based on the IEEE 802.16 standard, is designed to support a variety of applications,...
In this paper the use of IEEE 802.16 based networks for voice communications is considered. Specifically the system voice traffic performance is investigated in conjunction with the carrier grade QoS restrictions. The burstiness of voice traffic with VAD is taken into account. Analytical methods for carrier grade voice traffic over IEEE 802.16 system evaluation under different scheduling algorithms...
