Design And Implementation Of The Dual Terminal Communication System Based On Wireless Sensor Network

In the era of big data and mobile Internet,the ubiquitous interaction between objects is becoming more and more important.Moreover,the design and implementation of communication protocol is particularly critical.In recent years,near field communication technology has gradually become one of the most widely used interactive means in the Internet of Things.It is also the main technical support of Personal Area Network and Body Area Network.However,in Wireless Sensor Networks,how to give full play to the technical advantage of the near field communication and how to enhance the efficiency of diversified sensing data transmission are still the main problems that restrict its application.Based on the most typical technology in near field communication(ZigBee),a type of dual terminal communication system in Wireless Sensor Network is proposed in this thesis.Firstly,the overall communication architecture model is analyzed,and the main technical means and development platform for its implementation are also defined.Subsequently,we independently developed the relay node that could simultaneously store and forward the scalar and vector information.Then,we build the client platform for dual terminal communication of the scalar information transmission,and development the embedded code software of the single work and duplex communication respectively.On this basis,we have also completed the design of the relay node storage and forwarding process,and realized the multi-hop scalar sensing data uploading in the near field.Finally,in view of the transmission requirements of multimedia sensing data,we realize the dual terminal communication system for vector information transmission by designing the image receiving&processing algorithm.The experimental results show that the dual terminal communication system has strong transmission stability and robustness,and can better adapt to all kinds of application scenes.
