Abstract :
A medium access control (MAC) protocol that integrates both voice and data traffic in TDM/CDMA VSAT networks is proposed and investigated. Architecture of the VSAT network is described. For voice traffic, speech activity detector (SAD) is used, and for data traffic, WWW browsing traffic is considered. Dynamic code allocation strategy with QoS consideration is the key feature of this MAC protocol. Given a VSAT, data packets can be transmitted in the silence period of voice traffic. If talkspurt continues, the channel should be obliged to transmit voice instead of data. Simulation results arc given for pure voice call and voice/data integration traffic.
