In this paper, we propose a new scheduling algorithm for IEEE802.16 Broadband wireless Metropolitan Area Networks in TDD mode. Based on some known algorithms such as Modified Deficit Round Robin (MDRR), Proportional Fairness (PF) and Adaptive Proportional Fairness (APF), we have studied the scheduling problem and proposed scheduling algorithm, called (Enhanced-APF) for focuses on an efficient mechanism...
In this paper we propose a novel technique for efficient video distribution over WiMAX networks. The technique incorporates resource distribution, scheduling and content-aware streaming of video taking advantage of a flexible QoS functionality offered by WiMAX. The proposed technique was thoroughly investigated using NS-2 software package under various real-life scenarios which included streaming...
We propose a resource allocation algorithm that provides enhanced QoS and efficiency for layered video multicast over mobile WiMAX. The application is characterized by groups of users acquiring popular video programs over a fading channel. To accommodate various bandwidth requirements and adaptive perceptual quality to different users, video streams are coded into base and enhancement layers using...
IEEE 802.16, popularly known as WiMAX, is one of the most innovative methods developed in recent times to address growing demand for high-speed wireless broadband networks. This paper addresses the problems concerning the delivery of video packets in video conferencing and other multimedia application services over WiMAX. Multiple competing traffic sources over a point-to-multipoint WiMAX topology...
