Abstract:This article describes in detail the topology structure of star wireless sensor network (WSN). And the hardware platform of sensor node composed of temperature sensor DS18B20, SCM(single chip microcomputer) AT89LV51, and wireless module PTR8000 and the hardware platform of sink composed of SCM(single chip microcomputer) AT89LV51, embedded general-purpose processor S3C2410 and wireless module PTR8000 are also shown. In the software system, according to specific network topology structure and hardware platform, the wireless serial communication protocol between the sensor node and sink and the design of serial communication protocol between the master microprocessor control unit (MCU) and slave microprocessor control unit (MCU) of interior of sink are designed. This paper discusses the flow of data in the system and the designs of software system in sensor node and sink.
Keywords:WSN  star  wireless communication  serial communication  protocol
