Low Power Consumption Of Wireless Sensor Networks Secure Communications Technology To Explore And Achieve

Wireless Sensor Network(WSN),which is made by the convergence of sensor , nested computation, networks and wireless communication technologies, is a novel technology about acquiring and processing information. It could be used for testing, sensing, collecting and processing information of monitored objects in time, and finally send them to the customers who need them. WSN is a new research area of computer science and technology and has a wide application future.In WSN, Network Secure Communication is getting high status in network communication area, Key Distribution protocol is one of significant components for security defense on WSN transmission. Due to the special properties of WSN, such as large scale,low resource,distribution and so on, traditional Key Center for wired network isn't usable again. Author depict several kinds of typical Key Distribution protocols used for WSN, and then use TinyOS system simulating key distribute process.Reducing the source consume, and prolonging the WSN lifecycle is becoming the chief target of WSN, which was based on the assurance of Network Secure Communication. Therefore, author not only pay attention to key distribution protocol research and implementation, but also attend to build up a WSN simulated application structure. Choosing AODV routing protocol as under-communication protocol, combining data integration, cluster selection, cluster building and other techniques, author intend to realize WSN low-consuming network communication by various measures. In this article, author simulate the network structure by NS2 simulation platform, including data transmission,data collecting,data combination and so on. Author describe the whole process of WSN communication, finish the low-consume research on WSN from another point of view.
