摘要
为了在实际信道条件下研究无线传感器网络中的双优先级MAC协议,提出了一种基于现场可编程门阵列(FPGA)的硬件电路实现方案.首先运用平均周期法建立数学模型,求得双优先级P坚持CSMA协议的吞吐量与节点平均功率理论值;然后运用Verilog HDL依据协议控制原理设计相应功能模块,建立了稳定传输的电路系统.电路实验的仿真值与理论值一致,证实了该设计方案实现准确率较高,实时传输性能好等特点.
In order to study the dual-priority MAC protocol in Wireless Sensor Networks under actual channel conditions,the hardware circuit implementation scheme based on Field Programmable Gate Array（ FPGA） is proposed.First,the average cycle method is used to establish a mathematical model according to the P-persistent CSMA,and the throughput and the average power of nodes are obtained. Then the corresponding functional modules are designed based on protocol control principle using Verilog HDL,and a stable transmission circuit system is established.Finally,the simulation value is consistent with the theoretical value,which confirming that the design scheme has the characteristics of high accuracy and good real-time transmission performance.
