Design and Realization of Virtual Instrument Based on IEEE 802.15.4 Protocol

The wireless sensor networks analyzer based on IEEE 802.15.4 protocol was designed and realized by using virtual instrument technology. The data frame analysis and real-time display of the network topology were realized by using the MVC design pattern which separated the user interface and the business logic processing of the software modules. What's more, the scalability of the application was improved. In order to handle the data from the serial port and improve processing quality, a method of data processing based on adaptive thread pool technology was realized. The practical result showed that the analyzer mets the needs of the system design and has large significances on the theory and application of wireless sensor networks.
