Optimization And Practice Of Wireless Sensor Network

Wireless sensor network technology is a comprehensive technology of information technology, sensor technology and integrated circuit technology.. With the rapid development of modern information technology, sensor technology and circuit integration technology, there are a lot of major breakthroughs before wireless sensor network technology.. But due to the increase in the requirements of the system in wireless sensor network, especially for different application scenarios, sensor nodes and sensor data, and an increase in its interference in different application environments, which give stable and robust performance of the wireless sensor network system bring new opportunities and challenges.This paper designs and practices the intelligent campus wireless intelligent course management system for the practical project.. From the point of view of practical application, the characteristics of wireless sensor network are introduced, and the hot issues and solutions of wireless sensor network are analyzed and introduced.. "Based on cluster structure of the improved directional routing algorithm. The algorithm combines the clustering routing algorithm in energy efficient and easy to implement in network data fusion, and directed diffusion routing algorithm in the data transmission process of performance optimization is proposed according to actual situation of the project encountered (on the large amount of data, the number of nodes are large, but the energy consumption of the system requirements are not particularly high system). And directed diffusion routing algorithm for path to establish the need for multiple broadcast in the network delay is longer and clustering routing algorithm requires frequent changes in topology characteristics are improved and optimized. Finally, the improved clustering routing algorithm and directed diffusion routing algorithm integration, has reduced the system delay, improve the stability and robustness of the system, finally according to the system simulation and actual test results to prove the effectiveness of the algorithm and the advantages for such applications.Wisdom campus wireless intelligent course management system, is a can through the network server online update and manage the campus in each classroom curriculum planning system, in the system of each classroom door are equipped with a ZigBee gateway 7 inch touch LCD display system, through the ZigBee ad hoc networks to the classroom, all ZigBee gateway is connected to a WiFi and ZigBee gateway, so as to achieve each classroom node networking capabilities. Finally, the system is connected to the campus management network, the campus classroom curriculum online management, remote updates and other functions. The system integrates the ZigBee networking technology, low power WiFi technology and network communication technology is a technology platform development and improve the ZigBee turn WiFi signal in the 2.4G environment mutual interference. Have some research significance and practical application reference value.
