Abstract :
This paper proposes an integrated voice and data services (handshake-ALOHA) for CDMA wireless LANs. This protocol is designed to accommodate integrated services on CDMA LANs with quality of service (QoS). It uses a handshake procedure for voice calls first, followed by a reserved period for pure voice transmission. Then the remaining time of the frame is allocated to the data users for transmissions based on ALOHA protocol in nature. The length of data transmission period can be varied according to the number of voice calls initiated, voice packet length and the system threshold. Numerical results in voice call blocking probability, packet loss rate, and network throughput are presented, including comparison with the pure ALOHA protocol
