Node Design For Wireless Sensor Network And Communication Research Based On Zigbee Protocol

The sensor technology of acquiring information is the most important and elementary technology which opens the way to the integration, minisize and network from the singularity. Wireless sensor networks (WSN) is a novel hotspot of research field which has been made viable by the convergence of senor, embedded computing system, wireless communication technologies and distributed information processing. Both academia and industries are engaged in developing WSN due to the wide and potential future with various applications.This dissertation describes the concept of WSN. System structure, node technology and protocols of networkof wireless sensor networks are explored as the research work of the beginning. The characteristics and some crucial problems of the WSN are summed up. Classifying reseach and analyze of the protocols of data link layer and network layer are carried out. Then, the protocol structure and characteristics of the wireless communication protocol Zigbee are introduced in detail. It was proposed that basic frame of the all-purpose node in the wireless sensor network (WSN) based on the principle of design. The solution and practical implementation of hardware structure and software of the system is provided, and a good consideration of its low power consumption on the fact of hardware and software was outlined. At last, the tache of the experiment is designed to test and analyze the some capabilities. The experimental results show that the design of the all-purpose node platform in the text for wireless sensor networks is feasible solution of low price and low power consumption. The system can realize wireless communication between the sensor nodes at lower power consumption.
