Analysis and Design of Collision Avoidance Optimization Algorithm Based on CSMA/CA

摘要

Carrier Sense Multiple Access is a media access control protocol with two contention types in wired network and wireless networks. This paper compares CSMA/CA and CSMA/CD competition modes, introduces and analyzes the existing collision avoidance algorithm, and designs a CSMA/CA collision detection avoidance optimization algorithm based on scheduling algorithm and backoff algorithm. The optimization algorithm focuses on important indicators such as priority, throughput, turnaround time and fair balance and so on, and then the efficiency of the algorithm is further improved.
