A new protocol for the integration of voice and data over PRMA

A new scheme for the integration of voice and data based on PRMA is proposed. The voice and the data subsystems are logically separated. The total available bandwidth is divided into three regions-voice information, voice contention, and data regions. The bandwidth available for the data users depends on the fulfilling of the QOS requirements for the voice users, which is assumed to be a limit on the number of dropped voice packets. The voice subsystem has been modeled as a Markov chain and an optimization problem to maximize the bandwidth allocated for the data users has been formulated. Numerical results indicate that a significant amount of data traffic can be supported without sacrificing the voice capacity of the system.
