【Abstract】 In this paper we propose a novel bandwidth scheduling algorithm for real time polling services (rtPS), the SS estimate the arrival of rtPS packets prior to the arrival and requests the BS for bandwidth in advance, based on the SS’s request and the indeed bandwidth request by past, and then schedule the packets. The analytical model and simulation show that, this adaptive algorithm provided better results with respect to the number of packets waiting at SS and average delay as compared to the widely accepted weighted scheduling algorithm.更多还原
