The Design And Implementation Of Wireless Sensor Network Node Chip

Form 1990s, with the development of embedded system, wireless communication, internet and micron mechanism system technology, the sensors with apperception, calculation and wireless network communication ability and wireless sensor network attract very great interest. Because of self-organizing, lower power, lower cost feature, Wireless Sensor Network has become a hot research topic with high value in theory and application field. The technology of wireless sensor chip is reviewed as the most import information technology in 21 century by USA Commerce Weekly and MIT Technology Review.The research status of Wireless Sensor Network lags relatively in our country. The development of Wireless Sensor Network is not only benefit for national defense, but also good for society and economy.However, there are still some challenges in power cost and security field of Wireless Sensor network. Wireless channel is easily wiretapped and disturbed, and mobile node makes network topology so frequencely changing to make it easily attacked. On the other hand, wireless Ad hoc network nodes normally are mobile devices with battery supply, so the power problem becomes a key point which limits usability of network.Fujiang province import science plan project"Wireless Access Chip"is the background of this paper. The purpose of this project is to design both hardware and software of Wireless Sensor Network, include network hardware design, network protocol implement and wireless sensor network node chip design.This paper research the theory of Wireless Sensor Network, design and implement Wireless Sensor Network node chip according with self-develop Wireless Sensor Network scheme in the perspective of low power, low cost and security.
