Performance evaluation of a reservation TDMA protocol for voice/data transmission in personal communication networks with nonindependent channel errors

This paper deals with a random reservation TDMA protocol able to support co nstant bit-rate services as well as variable bit-rate services. In particul ar, we consider here the case of voice communications and data transmission s in a fading channel environment with nonindependent errors. Voice termina ls are assumed to have higher priority than data terminals, in accessing th e shared channel. A suitable analytical approach is proposed in order to ev aluate the data and voice subsystem performance. Computer simulations are a lso shown in order to validate the obtained analytical predictions. The res ults shown here highlight that the proposed protocol permits an efficient i ntegration of voice and data transmissions in the same wireless network eve n in the presence of a nonideal transmission channel.
