The IEEE 802.16 j standard proposes a multihop relay network architecture that introduces
relay stations aiming at increasing the network throughput or coverage. The deployment of …

IEEE 802.16 j standard defines Relay Station (RS) to enhance network throughput.
Deploying RSs within the serving area of the Base Station (BS) could increase network …

The user-perceived performance of voice services can be improved if the handover (HO)
criterion is designed to consider the mean opinion score (MOS). However, this involves …

WiMAX, as supported by standard IEEEE 802.16, is an emerging broadband wireless
access technology which can provide good features including high transmission rate and …

This paper introduces the performance analysis of VoIP applications over WLAN. The factors
of VoIP quality include the voice codec, delay, jitter, and packet loss rate. The MOS and E …

This paper proposes silence drop first (SDF) active buffer management algorithm to increase
the voice capacity when silence suppression is used. This algorithm finds and drops silence …

Abstract The Relay Station (RS) deployment problem for WiMAX networks is studied. Unlike
Base Station (BS), RS does not need a wire-line backhaul and has much lower hardware …

This paper proposes silence drop first algorithm (SDF) for the active buffer management.
This algorithm finds and drops silence packet rather than talkspurt packet in the queue for …
