Performance analysis of multichannel reservation random access protocol for mobile cellular network
Jae-Soo Kim, I‐Shyan Hwang · 2002
Two multichannel media access protocols with different frequency channels for a mobile cellular environment are investigated. MPRMA is a multichannel PRMA protocol and MSAC is a multichannel protocol with a slotted ALOHA based control channel. Fixed total bandwidth is used. For integrated services and different quality service requirements, only the voice packet can reserve the future slot during talkspurt when the information packet is transmitted successfully. A semi-Markov model was developed to study the operations of the protocols. The comparisons of these protocols are investigated through analytical models as well as discrete-event simulation in terms of the number of simultaneous users, packet dropping probability with the variations of the number of channels and the information packet size.
