Abstract

The development of wireless communication technology has become increasingly important in the communications industry. How to allocate limited channel resources reasonably and reliably to each competing user is a problem that the access protocol of the MAC (Multiple Access Control) layer needs to solve. As an important way of random access, NP-CSMA (Non Persistent Carrier Sense Multiple Access) has a higher network throughput rate when the arrival rate is higher. This paper analyzes and improves the implemented NP-CSMA model, and obtains a three-slot NP-CSMA model. The mathematical tool MATLAB is used to analyze the network throughput, delay and energy efficiency of the model, and compare several random multiple access protocols adheres to the network throughput, they are NP-CSMA, Three-slot NP-CSMA, 1-persistent CSMA, P-persistent CSMA, and concludes that the three-slot NP-CSMA is significantly letter than several other multiple access protocols. Finally, using Quartus to design the three-slot NP-CSMA circuit, the statistical value of the circuit system is compared with the theoretical value of the model, and the error is less than 0.01, which proves that the system is reasonable in design and can be applied to wireless communication networks.
