Enhancements in CSMA/CD and CSMA/CA for Collision Handling in Ethernet and Wi-Fi Networks

Carrier Sense Multiple Access with Collision Detection (CSMA/CD) and Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) are fundamental access control mechanisms used in Ethernet and Wi-Fi networks, respectively. However, as network traffic grows and devices become more interconnected, traditional implementations of these protocols encounter inefficiencies, leading to increased collision rates, network congestion, and higher transmission delays. This paper explores recent advancements in CSMA/CD and CSMA/CA aimed at improving collision handling, reducing packet loss, and optimizing network performance. Techniques such as adaptive backoff algorithms, machine learning-based collision prediction, hybrid access control schemes, and full-duplex communication are analyzed in detail. Furthermore, simulations conducted using NS-3 demonstrate improvements in network throughput, reduced latency, and enhanced reliability in both Ethernet and Wi-Fi environments. The findings indicate that integrating adaptive and intelligent mechanisms into these protocols can significantly enhance the efficiency of modern communication networks, making them more robust for high-traffic applications, IoT deployments, and real-time data transmissions.
