Security And Interference Analysis Of Environmental Monitoring System Based On ZigBee

The ZigBee technique is a wireless sensor network standard, developed by the ZigBee alliance, which is characteristic of short distance, low power, low cost, low complexity and low bit rate etc. And this standard is mainly suitable for automatic and remote control. The ZigBee technique standard is based on IEEE 802.15.4 low bit rate personal wireless area network. And then supports Media Access Control (MAC) layer and physical layer standard, also includes network layer and application layer on this foundation.After the analysis of situation about pollution and environment monitoring, this paper aim to design a low cost, low complexity system, which can satisfy user's special need, to carry on to the environment data in long-term. According to application of this system, this paper has a deep analysis on security and interference, and then gives some solutions on the basis of application.In all, this paper pays attention to system design of environment monitor and analysis of security and interference. Innovation mainly appears in the following aspects for this paper.●According to the need of user and development of monitor technique, proposed the scheme design of environment.●Base on thorough analysis of ZigBee security, find deficiency and problem of this system, and then give scheme to solution the problem.●According to the application scene, put forward advance based on thorough analysis of ZigBee interference.
