A novel polling-based scheduling approach for an efficient radio resource sharing in wireless networks

This paper proposes novel scheduling techniques to support real-time traffic and data bursty traffic under quality of service guarantees. In particular, two polling-based approaches are compared: (i) when a source is enabled to transmit, a burst of packets is sent at once; (ii) within the time interval destined to a traffic class, a cyclic service of the sources is allowed on a packet basis. Considering both radio channel conditions and protocol signaling overhead, this paper compares these two different approaches and the dynamic slot assignment++ (DSA++) scheme appeared in the literature, showing that our second scheme (case ii) achieves a good performance.
