Design and implementation of no-persistent CSMA based on FPGA

Abstract

CSMA is carrier-sense multiple access and is one of the key protocols to ensure the efficient operation of the communication network. According to the characteristics of wireless sensor network nodes, the use of FPGA (field programmable array) for no-persistent CSMA access communication system provides a high-speed data transmission scheme to achieve gate. The design uses MATLAB and Quartus II as the experimental platform, which satisfies the Poisson distribution and the time slot length controllable source module for different events in the transmission process, using the method of hardware description language Verilog HDL and logic circuits to design the simulation, through calculation and analysis, the theory of throughput of the protocol are consistent with the simulation value, proved that the system has reliability design bureau, portability etc.
