Abstract

The IEEE 802.16 system provides the power saving class (PSC) type II as a power saving algorithm for voice over internet protocol (VoIP) service, but it is not designed to consider silent periods of VoIP traffic. The main objective of this paper is to introduce a power conservation mechanism that combines power saving modes class I, class II and class III which is applicable to VoIP service with silence suppression which basically follows PSC II during talk-spurt periods but in silence periods it combine PSC I and PSC III. According to experimental results, more than 96 % power reduction can be achieved in mutual silence period by using the proposed VoIP power saving mechanism for VoIP services during silent periods with respect to the Quality of Services.
