A real-time algorithm for fixed-length short data compression

Based on the specialties of the transmission of fixed-length short data in certain special industries, the lossless compression algorithm for the fixed-length short data packets is presented. The iteration procedure is used to explore the rules rightward and downward from the source data packet and the compression dictionary is obtained. It overcomes the shortcoming of the traditional compression algorithm which only compresses the data by file, but cannot compress the short data effectively by packets. Only the compressed packet but not the compression dictionary is transferred in the network. The experimental results show that the proposed algorithm also overcomes the shortcoming that the Lempel-Ziv-Welch (LZW) algorithm cannot compress the data by pockets. This lossless compression algorithm can effectively compress the fixed-length short data which has similar structure and massive repetition. It realizes compressing and transfering the packets effectively and securely.
