1 A Method for Non-real-time Polling Service in IEEE 802.16 Wireless Access Networks + Jing Wu, + Jeonghoon Mo, and * Ting Wang + Information and Communications University (ICU) Daejeon, South Korea * School of Information Engineering Beijing University of Posts and Telecommunications Beijing, China

2 Agenda Introduction Proportional Fair Scheduling (PFS) Modified Proportional Fair Scheduling Based Polling Simulation Results Conclusion and Future Works

3 Introduction -Problem & Motivation Providing comprehensive QoS guarantee for different types of traffics is one of features in IEEE 802.16 system Polling method in the UL remains an open issue Round Robin polling Proportional Fair Scheduling (PFS)

4 Introduction -Goal QoS Guarantee Provision for nrtPS Uplink Polling Method Design Minimum reserved traffic rate Maximum sustained traffic rate

5 Proportional Fair Scheduling (PFS) Priority Function The priority for user i in slot t is calculated by the formula A. Jalali, R. Padovani and R. Pankaj, “Data throughput of CDMA-HDR a high efficiency-high data rate personal communication wireless system”, In Proceedings of VTC 2000, vol. 3, pp. 1854 - 1858, May. 2000. The rate requested by user i The average rate received by user i over window of appropriate size T c

6 Modified Proportional Fair Scheduling Based Polling (MPFS) - User Classification SS 1 SS 3 SS 10 SS 9 SS 8 SS 6 SS 2 SS 7 SS 4 Deficit Group ( AVG i < R min ) Surplus Group ( AVG i > R max ) Common Group ( R min < AVG i < R max ) DRC 1 = 3 DRC 3 = 7 DRC 2 = 5 DRC 4 = 9 DRC 6 = 36 DRC 7 = 58 DRC 8 = 21DRC 9 = 24 DRC 10 = 32 AVG 1 (t)=10AVG 2 (t)=20 AVG 3 (t)=30AVG 4 (t)=40 AVG 7 (t)=70 AVG 6 (t) = 60 AVG 6 (t) = 80 AVG 6 (t) = 90 AVG 6 (t) = 100 Polling Order

7 Modified Proportional Fair Scheduling Based Polling - Average Rate Calculation R i (t) The average rate received by user i over a window of appropriate size T c Exponentially Weighted Average The past information The weighting factor for the past slots The weighting factor for the n-th previous slot

8 Simulation Simulation Environment Simulator: NS-2 TDD Model Frame size: 5 ms Time Domain Downlink subframe = 27 symbols Uplink subframe = 15 symbols Frequency domain Subchannel Number = 16 1 subchannel (FUSC) = 48 subcarriers Traffic load > wireless system capacity

9 Simulation -System Throughput for Three Polling Methods Simulation Results

10 Simulation -User 1 Average Throughput Simulation Results

11 Simulation -User 3 Average Throughput Simulation Results

12 Conclusion This paper proposed a practical method for nrtPS services in IEEE 802.16 Modified Proportional Fair Scheduling Based Polling The simulation results confirm the effectiveness of methods
