认知无线电传感器网络在食品生产中的应用

Research on application of cognitive radio wireless sensor networks in food production

无线传感器网络被广泛地应用于食品安全生产和检测中,传感器信息准确地捕捉是此类系统的关键。利用认知无线电技术能有效解决在食品安全生产和监测系统中基于RFID技术的无线传感器网络信号干扰和信道拥堵的问题,并通过MATLAB的仿真结果证明所建立系统模型的合理性。

Wireless sensor networks are facilitated in detecting food security and production.The key of this system is to capture the information from sensors without error.The idea of Cognitive Radio network（CRN）is used to eliminate signal interference and channel jamming in wireless sensor networks based on RFID and simulation results in Matlab shows that the modeling and analysis are valid.
