A Heuristic EDF Uplink Scheduler for Real Time Application in WiMAX Communication

Provided by: International Journal of Advanced Research in Computer Science and Software Engineering (IJARCSSE) Topic: Networking Format: PDF
WiMAX, Worldwide interoperability for Microwave Access, is a developing wireless communication scheme that can provide broadband access to large-scale coverage. WiMAX belongs to the family of standards of IEEE-802.16. To satisfy user demands and support a new set of real time services and applications, a realistic and dynamic resource allocation algorithm is mandatory. One of the most efficient algorithm is EDF (Earliest Deadline First). But the problem is that when the difference between deadlines is large enough, then lower priority queues have to starve.
