Abstract

Slotted multichannel non-persistent CSMA/CD (carrier sense multiple access with collision detection) radio LANs with a finite number of stations are considered. A multichannel packet radio network is based upon frequency domain design techniques which reallocate the system bandwidth. Markov chain analysis is used to exactly derive the moment generating functions (m.g.f.s) of the output process and interdeparture times. Channel utilization, delay performance and higher moments are then calculated in terms of the number of network stations, the number of network channels and the channel access rate. Calculated results show that the multichannel CSMA/CD not only preserves preferable features of the single channel CSMA/CD, but also has advantages such as extensibility of capacity, effectiveness, reliability, adaptability and serviceability over the single channel case. These results can then be used to evaluate the performance of interconnected networks, multi-hop multichannel networks or integrated networks of voice and data.
