Design of Wireless Sensor Network Node Based on CC2431

CC2431 is a novel wireless radio chip introduced by Chipcon which meets the Zigbee standard and has the function of localization. The node designed can provide hardware location service with high quality for WSNs. After briefly introducing the wireless sensor networks and features of the nodes,this paper de-scribes the performance and characteristics of CC2431 in detail,and by taking the peripheral interface and electric characteristic of CC2431 into consideration,the node is designed using modularized technique and realized a specific wireless sensor node based on CC2431 which integrates the 8051 processor and wireless radio communication module.
