Design and implementation of probability detection CSMA based on FPGA

基于现场可编程门阵列(FPGA)电路设计为概率检测载波侦听多路访问(CSMA)协议提供一种实现方案。根据协议控制原理,讨论了设计的难点和设计方案。运用MATLAB与Quartus两种软件,生成满足泊松分布的信源模块,同时结合发送状态长度控制与选择性读取等模块搭建了系统电路。测试结果表明系统电路的吞吐量、节点能耗的统计值与理论值一致,证实了该设计的正确性、稳定性等特点,能够体现协议的高效传输特性。

FPGA-based circuit design provides a realization scheme for probability detection carrier sense multiple access( CSMA) protocol. According to the principle of protocol control,the difficulty and design scheme of the design are discussed. Using MATLAB and Quartus generate Poisson distribution to meet the source module,combined with the transmission status length control and selective read the module to build the system hardware circuit. The test results show that the throughput and average power of the system circuit are consistent with the theoretical value,which proves the correctness and stability of the design and can reflect the efficient transmission characteristics of the protocol.
