MATLAB Implementation of Non-Persistent CSMA Protocol

In computer networks, Non-Persistent Carrier Sense Multiple Access (CSMA) protocol is a data communication protocol that evaluates network performance by calculating actual generated traffic, throughput, and average delay. The protocol employs channel sensing before transmission and implements random backoff algorithms upon detecting channel busy states. MATLAB implementation typically involves modeling packet generation processes, channel state monitoring, and collision detection mechanisms using timer functions and probability distributions. The CSMA protocol helps ensure smooth data transmission and efficient processing through its carrier sensing and collision avoidance features, thereby improving overall network performance and efficiency. Key implementation aspects include traffic generation using Poisson processes, throughput calculation based on successful transmissions, and delay computation accounting for waiting times and retransmissions.
