DesignandImplementationofTime-slottedRandom MultipleAccessProtocol UsedinWirelessSensorNetwork

简要介绍分析了时隙式随机多址协议,并利用Matlab软件对时隙式随机多址协议进行了分析和仿真,软件仿真结果与理论结果一致。为了在无线传感器网络中实现时隙随机多址协议,在设计过程中选择CC2530作为硬件平台,修改Zstack协议栈,并使用计算机保存数据包发送和接收的状态,结合python分析处理所测的数据。使用吞吐量作为评价系统的重要指标,与理论值相比,实际硬件仿真的实验结果与理论结果基本相符合,与matlab仿真结果基本一致,为在无线传感器网络中其他更复杂的随机多址协议实现奠定了基础。

This paper briefly introduces the time-slotted random multiple access protocol,and uses Matlab software to analyze and simulate the time-slotted random multiple access protocol.The software simulation results are consistent with the theoretical results.In order to implement the time-slot random access protocol in the wireless sensor network,CC2530 is selected as the hardware platform in the design process,the Zstack protocol stack is modified,and the state of data packet transmission and reception is saved by using the computer,and the saved data is processedand analysis combination with python.The analysis uses throughput as an important indicator of the system.Compared with the theoretical value,the experimental results of the actual hardware simulation are basically consistent with the theoretical results,which lays a foundation for the implementation of other more complex random multiple access protocols in wireless sensor networks.
