Design Of Wireless Sensor Networks Node Based On TinyOS

The wireless sensor networks (WSNs) are the hotspot reaserch of current wireless communiction technology.It is the foundation of theory reaserch and product development that constructing a wireless sensor node with independent intellectual property rights.General laws and methords of constructing a wireless sensor node is discussed in this thesis from two aspects:hardware and software.A design of wireless sensor node hardware platform is proposed,which is based on CIP51 micro-controller and one RF chip with independent intellectual property rights.Upon this platform using TinyOS as embedded operating system,hardware driver is designed which will offer interfaces such as configuration and sending/receiving to upper software layer.A kind of wireless sensor node is constructed which is compatible with exsiting WSN communication stack in TinyOS.In the end of this thesis the node is tested in experiments.Further research of theory and product could be done based on this node.
