| Abstract: | This paper focuses on low bit rate wireless applications like video conferencing and visual telephone, and proposes a new scheme--pseudo reservation scheme for the integration of video, voice and data transmission based on Packet Reservation Multiple Access wireless networks. With the packet dropping probability of the active voice terminals, the system bandwidth utilization performance is superior to the original PRMA without sacrificing the video capacity. |
