Abstract:

To address when multiple users through a common channel to communicate with other users must use multiple access technologies. Slotted ALOHA in the elaboration of the ALOHA system and the continuous-time systems as well as non-persistent CSMA (Carrier Sense Multiple Access) control protocol, while the analysis were obtained three kinds of systems, the average successful captain and system throughput mathematical expression, and through simulation experiments verify the theoretical analysis is correct.

Key words: stochastical multi-addresses, signal channel, loop body, average period, throughput
