Based On Zigbee Wireless Sensor Network Research

In recent years, with the government and national business support, "wisdom of the Earth" and "Sensor China" and other strategic slogans have been made, things related industries are ready to go.2010 was the networking industry as China's first year, the government and enterprises have invested a lot of its resources, and hope to cultivate after the Internet became another big emerging information industry. ZigBee technology to support the networking industry as one of key technologies, explosive growth has been listed as the world's fastest-growing, broad market prospects of the top ten most recent technologies.Wireless sensor network applications have their specific and unique network architecture, network protocols, making it a wireless sensor network technology, the most fundamental requirements. Because of its low power, low complexity, multi-hop and self-organization characteristics, and other areas, making the ZigBee wireless sensor network technology and the perfect blend, while ZigBee protocol wireless sensor network is becoming the preferred communication protocol.In this paper, based on the ZigBee wireless sensor network research, IEEE 802.15.4/ZigBee standards and by analyzing the SOC technology, ZigBee protocol stack application of simple short-range wireless sensor networks. This research focused on the following three aspects:(1) A brief research and analysis of wireless sensor networks and introduces the basic concepts of ZigBee technology, focusing on wireless sensor network architecture, applications, and the combination with the ZigBee protocol. The results show that:ZigBee wireless sensor network technology will become the preferred protocol standards.(2) Focuses on the analysis of the ZigBee protocol stack. Its protocol stack architecture for a systematic analysis, including the physical layer, MAC layer, network layer, application layer and the ZigBee security. Finally, based on the ZigBee protocol analysis technique based on ZigBee wireless sensor network design hardware and software requirements. (3) To achieve a temperature based on the ZigBee wireless sensor network technology. Flying Technology Co., Ltd. of Shenzhen over the CC2530MDK ZigBee development kit, the coordinator to establish network terminal sensor nodes join the network and other in-depth study of ZigBee technology networking process. And Z-Stack protocol stack, based on the realization of a simple star topology wireless sensor network system, the temperature information collection and display through the serial port, designed to achieve the desired purpose, the completion of the overall requirements of the temperature acquisition.
