Abstract :
Making full of multi-polling technique and the silence characteristic of VoIP service, a new Extended rtPS uplink scheduling algorithm is proposed based on IEEE 802.16e system. Via analysis of theory and simulation, the proposed algorithm has superior performance in view of throughput and capacity at the same time it hsa little influence in the delay requirement of VoIP service.
