Improving ertPS Grant Allocation for VoIP Traffic in Silence Duration

S. Amir. Hoseini, S. Saed Rezaie, and H. Taheri

Abstract—This paper proposes a new uplink scheduling algorithm that can increase the uplink VoIP user capacity for ertPS scheduling in 802.16e networks. This algorithm solves the problems of uplink resources wastes and large overhead which causes during silence period. We compare our method with four related schemes including conventional ertPS. In these algorithms, efficient schemes are proposed to improve the uplink resource allocation procedure for ertPS scheduling. We use OPNET simulator to investigate delay, jitter and loss in our experiments. We show that our scheme improves the capacity by 20% while the voice quality is affected minimally.

Index Terms—802.16, ERTPS, scheduling algorithm, OPNET, VoIP, WiMAX.
