A VoIP focused frame aggregation in wireless local area networks: Features and performance characteristics

This paper proposes a frame aggregation scheme for VoIP traffic over wireless local area network. In this context, we studied main attributes of VoIP in wireless systems, and recalled its basic requirements when it comes to quality of service. We proved that voice streams particularity in terms of bandwidth, pattern and packet format has its own fallouts on the aggregation scheme. This involves basically the aggregation method, the aggregate exchange and the frame sizing. A well fitted aggregation implies a limited aggregate size range to append tolerable delays to higher efficiency. A performance analysis illustrated better response in terms of delay, delay variation and spectral efficiency compared to a legacy non-aggregate scheme.
