The authors consider a system comprising a finite number of nodes, with infinite packet buffers, that use unslotted ALOHA with code division multiple access (CDMA) to share a channel for transmitting packetised data. They propose a simple model for packet transmission and retransmission at each node, and show that saturation throughput in this model yields a sufficient condition for the stability of the packet buffers; they interpret this as the capacity of the access method. They calculate and compare the capacities of CDMA-ALOHA (with and without code sharing) and TDMA-ALOHA; they also consider carrier sensing and collision detection versions of these protocols. In each case, saturation throughput can be obtained via analysis of a continuous time Markov chain. Finally, they also present some simulation results for mean packet delay
