摘要
提出了一种改进型自适应Huffman编码算法,目的在于压缩传输数据的容量,该算法适用于内存和计算资源受限的无线传感网络节点。它与修剪树自适应Huffman编码算法[1]相比较,能够更有效地利用内存空间,提供更好的压缩比。
In this paper, a modified adaptive Huffman coding algorithm is proposed particularly suited to the reduced data volume and computational resources of a WSN node. The performance of the modified adaptive Huffman algorithm is analyzed and compared with the tailoring adaptive Huffman coding algorithm [1]. The results indicate that our algorithm can use memory more efficiently,and provide better compression ratio.
