PACKET OUTPUT PROCESSES OF CSMA AND CSMA CD PROTOCOLS/

This paper considers a generic CSMA and CSMA/CD protocol that allows o ne to unify the nonpersistent and one-persistent protocols as special cases, and solve the corresponding output characterization problem und er the infinite population model, Explicit expressions of the interdep arture time moment generating function, as well as expressions for the channel throughput and the variance of output process, are obtained f or both slotted and nonslotted cases, In addition to direct simulation results, we also provide a novel statistical analysis/simulation proc edure for the purpose of validating the infinite population model and the analytical results, Both approaches indicate that the infinite pop ulation model is quite appropriate for analyzing this generic protocol .
