WebWe study a CSMA/CA (Carrier Sense Medium Access with Collision Avoidance) wireless network where some stations deviate from the defined contention mechanism. By using Bianchi’s model, we study how this deviation impacts the network throughput and show that the fairness of the network is seriously affected, as the stations that deviate achieve … WebPerformance of CSMA/CD. It is simple to calculate the performance of a CSMA/CD network where only one node attempts to transmit at any time. In this case, the NIC may saturate the medium and near 100% utilisation of the link may be achieved, providing almost 10 Mbps of throughput on a 10 Mbps LAN.
