Study And Design On Smart Nodes Of Industrial Wireless Sensor Network

Wireless Sensor Network (WSN) has gained more and more attention from all over the world in recent years. A WSN node is small, low-cost and has limited computing ability and memories. WSN nodes communicate with each other via the wireless channels and form a network in self-organized manner to sense the information from the environment in collaboration and send it to the user. The WSN nodes and gateway that can be used in industrial fields are designed based on CC2430 from Texas Instruments (TI) in this paper; network management process is also designed. WSN nodes can communicate with sensors through RS232 or RS485. Meanwhile, they are also capable of communicating with the gateway via the wireless channels. The WSN gateway is responsible for the formation and maintenance of the network and the conversion of protocols between other networks and WSN.
