Overview:

Voice over Internet Protocol (VoIP) over a Wireless Local Area Network (WLAN) is poised to become an important Internet application. However, two major technical problems that stand in the way are: low VoIP capacity in WLAN and unacceptable VoIP performance in the presence of coexisting traffic from other applications. In actuality, no more than a few sessions can be supported due to various protocol overheads (for GSM 6.10, it is about 12). This paper proposes and investigates a scheme that can improve the VoIP capacity by close to 100% without changing the standard 802.11 CSMA/CA protocol.
