Long Sheng-chu · Journal of Zhejiang University of Technology · 2014
In wireless sensor network,communication will consume the most of node energy,how to effectively reduce the amount of communication is one of the directions in the wireless sensor network energy efficiency research.Aiming at sensing data with features of massive data,large redundancy,and the method of data compression can effectively remove redundant data and reduce the amount of data transmission in network.This paper designed animproved compression algorithm, which combines the lossy compression based on the longest straight line approximation with the classic Huffman algorithm.Experimental results show that this combination of compression algorithms can get a higher compression ratio.
