Scheduling deadline driven packet flows in HiperAccess

• Wireless communication systems are by nature and by regulations limited in bandwidth and hence capacity. Services with high demands on quality of service (QoS) will enforce high demands on the available capacity. This observation motivates the development of schedulers that can deliver the required QoS as well as being resource efficient. In this paper, we provide expressions of the worst case delivery time for schedulers based in the first in first out (FIFO) and the earliest due-date (EDD) principles which are applied to the HiperAccess point-to-multipoint radio communication system. Further, we propose modifications of the schedulers, which are more resource efficient at the expense of rare deadline misses. Despite the deadline misses, the modified scheduling algorithms can still provide an average delivery time well within the required deadline
