WiMAX systems are beginning to spread as a wide-area wireless access technology that provides QoS support for future multimedia applications. Vendors have started to ship off-the-shelf hardware that addresses the market of broadband Internet coverage in sparsely populated areas. Facing a potentially large deployment of 802.16-based end-system connectivity, it is of vital interest to experimentally...
Satellite networks are an attractive solution to provide broadband communication services anytime, anywhere with quality of service support. The aim of this paper is to study the integration of GEO satellite networks, DVB-RCS- based, with WiFi networks. This is particularly important in emergency scenarios where reliable satellite networks could be integrated with WiFi systems for local mobility support...
In this paper, we propose a new packet scheduling algorithm for IEEE 802.16 wireless access systems running time division duplex (TDD) mode. We compare the performance of the proposed algorithm to others in terms of bandwidth and fairness in details. The simulation results show that not only the newly proposed algorithm can handle the dynamic bandwidth allocation to achieve higher throughput, but...
