The design of an efficient scheduling mechanism for providing QoS in IEEE 802.16e is usually left to the designers and is a serious challenge for system developers. The performance of various services catered by WiMAX depends on a proper scheduling algorithm combined with a proper mapping and encoding scheme. The contribution of this work is twofold. The first is that we infuse an efficient scheduling...
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...
Growing bandwidth demand in the Internet requires new algorithms and architectures to provide a high degree of QoS. Further, to complicate the problem of Traffic Engineering, real time data processing requires more priority than non-real time data processing. In this paper, we present an effective solution for improving QoS of audio and video packets in MPLS networks under real time traffic conditions...
Multi media stream service provided by broadband wireless networks has emerged as a important technology and has attracted much attention today. Due to its large coverage area, low cost of deployment and high speed data rates, WiMAX is a promising technology for providing wireless last-mile connectivity. Physical and MAC layer of this technology refer to the IEEE 802.16e standard, which defines 5...
