Wi-Fi MAC Layer MATLAB Source Code Implementation

The Wi-Fi MAC (Media Access Control) layer serves as a fundamental component in wireless networking systems, responsible for managing medium access coordination and ensuring reliable data transmission. This MATLAB implementation provides researchers and engineers with a versatile platform for simulating MAC layer operations and analyzing performance metrics under various network conditions. The codebase includes key functionalities such as carrier sensing mechanisms, frame synchronization algorithms, and collision avoidance protocols following IEEE 802.11 standards. Researchers can leverage this implementation to model different access schemes including Distributed Coordination Function (DCF) and Point Coordination Function (PCF), with configurable parameters for backoff algorithms and network allocation vectors. The modular architecture allows for easy integration of new MAC protocols or modifications to existing ones, supporting performance evaluations through metrics like throughput analysis, latency measurements, and packet error rate calculations. The simulation environment includes event-driven scheduling mechanisms and state machine implementations for accurate protocol behavior representation. Key functions include: - CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) implementation with exponential backoff algorithms - Frame encapsulation/decapsulation utilities supporting various frame types (data, control, management) - ACK/NACK handling mechanisms with timeout configurations - Network simulation components for multi-node scenarios with configurable traffic patterns This resource enables deep exploration of wireless networking principles and facilitates the development of enhanced MAC layer protocols through practical code modification and experimental validation.
