Performance analysis of nonpersistent idle-signal casting multiple access with collision-detection (ICMA/CD) protocol

In land mobile-radio networks, nodes cannot sense the carrier transmitted from other nodes. Idle-signal casting multiple access with collision detection (ICMA/CD) is a centrally controlled multiple-access protocol in which a base station senses a shared inbound channel (node-to-base station) and broadcasts the channel information on a separate outbound (base station-to-node) channel. A nonpersistent ICMA/ CD protocol with the finite population model is analysed. Throughput is analysed for generally distributed packet lengths by using the discrete-time Markov chain.
