Implementation And Application Of ZigBee-2006 Protocol Stack

ZigBee is an open international standards-based novel short-range wireless communication technology with cost-effective,low-power consumption,low data-rates,low-complexity and high reliability,which has very broad application prospects on Energy Management and Efficiency,Home Automation,Building Automation,Industrial Automation and Wireless Sensor Networks.ZigBee has become a research and application hotspot currently.However,the domestic development of ZigBee is not good enough.Although there are some related hardware and software vendors,the protocol stacks running on their hardware are generally based on foreign commercial protocol stacks or simplified free protocol stacks.The lack of study and research platform for ZigBee technical details caused by the above-mentioned situation may also affect the domestic development of ZigBee technology in return.This paper provides a implementation of ZigBee-2006 protocol stack with some function cut-off from the view of technical research and practical application.The ZigBee hardware platform is constructed with Freescale's SiP MC13213.IEEE 802.15.4 standard and ZigBee-2006 specification are deeply studied and analyzed.This paper describes and implements the ZigBee PHY,MAC and NWK layer in detail,and analyzes the the root causes of SPI transaction protocol problem occurred in implementing the hardware driver.A highly efficient method is put forward to solve the problem of the management of numerous MAC PIB attributes.AODVjr algorithm is addressed to reduce the complexity of routing algorithm in ZigBee NWK layer,and the hierarchical routing is also supported since the use of distributed address assignment mechanism.Finally,a workshop devices monitoring system is carried out to verify the feasibility and correctness of the independent research and development hardware and software platform,and the low power consumption of the system is also analyzed and solved.The platform can be directly used as an independent module in practical project,and it also has a valuable reference value in offering as the basic platform for the study and research of ZigBee protocol.
