Paper Abstract

This paper proposes an integrated protocol of CDMA wireless LANs. Voice, data, and images can be exchanged over the wireless LANs based on this frame-based protocol. This protocol uses a handshake procedure for voice calls first, followed by a short polling/contention for data data/video transfer requests. Then, the formal transmission are allocated to voice users the higher priority, while the data/video transfers will not start until some random delay. The startup time of data/video transfer depends on the number of voice calls initiated and the system threshold. This protocol fully utilizes the characteristic of CDMA technique which allows simultaneous transmissions, while utilizes the movable boundary concept in TDMA to assure quality of service. Approximate performance analysis by assuming fixed packet length of both voice packets and data/video packets are proposed and numerical results in voice call blocking probability, packet loss rate, and network throughput are presented.
