Performance analysis of idle-signal casting multiple access (ICMA) protocols under pure Rayleigh fading and no capture

Abstract

Markov chain models are used to derive the average stationary throughput and delay performance of idle-signal casting multiple access (ICMA), with and without failure detection, protocols which are suitable for use in mobile packet radio local area networks, where propagation impairments are prevalent. The models consider the effects of pure Rayleigh fading on channel access and packet transmission. Numerical results, validated by computer simulations, are obtained that enable a quantitative study of the performance of the protocols.
