Compressed RTP performance for VoIP applications in IEEE 802.11 network / Mohd Zaimi Mohd Zin

Compressed Real-Time Transport Protocol (cRTP) is a protocol that can reduce the header in the VoIP packets. It's a point to point protocol and can be readily implemented on the WLAN (IEEE 802.11) networks. In this paper, the effectiveness of silent suppression (SS) and compression of RTP header applied to typical voice over 802.11 networks is being investigated by integrated simulations. Distributed coordination function (DCF) and point coordination function (PCF) networks are examined. The results shows that PCF distributed system are more suitable towards real time traffic. Reduction in packet sizes and packet count will give better perceived connection quality through shorter end-to-end delay and reduced packet loss.
