Design of Wireless Sensor Network Data Acquisition System via Health Sensor Based on Symmetric Encryption Algorithm

摘要

In order to improve the data collection effect of the wireless sensor network, a data collection system based on symmetric encryption algorithm is designed via health sensor. Upload the received data to the host via RS-232 to get the working mode and clock activity. The data acquisition circuit is designed with MSP430 module. The MapReduce programming model is used to complete data collection, a symmetric encryption algorithm is introduced, and a range data encryption query scheme with privacy protection function is designed. Apply it to the node data of the wireless sensor network to realize the secure data collection of the wireless sensor network. Experimental results show that the system has the advantages of high efficiency, large amount of data collection, and high residual energy of sensor network nodes.
