Analytic and Simulation Results for CSMA Contention Protocols.

Abstract

The behavior and comparative performance of the Listen-While-Talk (LWT) and Listen-Before-Talk (LBT) CSMA contention protocols are examined using analytic and simulation techniques. The equilibrium throughput and delay equations for the non-persistent LBT and LWT protocols are derived. Simulation results are provided for the 1-persistent LWT and LBT protocols as implemented on the MITRE coaxial cable system. The throughput and delay performance of the LWT protocol is demonstrated to be superior to that of other contention protocols for use in local networks. Dynamic control procedures, similar to those used in other contention systems, are applicable to LWT CSMA protocols. (Author)
