Abstract:With the rapid development of internet of things,internet of things equipment is showing explosive growth. There are more and more application scenarios using ZigBee technology for data acquisition. With the rapid growth of data volume,ZigBee wireless sensor(WSN)has exposed the shortcomings of high energy consumption,low bandwidth,high conflict and so on. Based on the characteristicthat Wi-Fi and WSN share 2.4 GHz frequency band,the article designs a cross protocol communication(CTC)algorithm to realize thedirect communication between ZigBee node and Wi-Fi node,which makes ZigBee node focus on data acquisition and Wi-Fi node realize datatransmission,so as to solve the above problems of traditional internet of things,and applies the algorithm to temperature acquisition system.
