Abstract :
The authors examine certain protocols for voice/data integration in hybrid satellite/terrestrial packet radio networks. In the ground subnetwork, code-division multiple-access with movable boundary in the code domain is used to serve the voice traffic and the retransmitted data traffic; on the satellite subnetwork, framed ALOHA with movable boundary is used for both data and voice. Based on a Markovian model of the system, the channel access protocols for both traffic types are analyzed. The performance of the above multiple-access schemes is evaluated in terms of voice and data throughput, voice blocking probability, and data delay. It is shown that splitting of retransmission traffic between the satellite and ground subnets increases the overall data throughput when the voice load is high
