Data compression can effectly save energy of network and prolong its life.Aimed at the defect of B-LZW algorithm
a modified compression algorithm for sensor nexworks—MC-B-LZW is introduced.The algorithm is enabled to be embedded in existing sensor network nodes by adding an miniCache module perfecting its maneuverability;test of the performance index for B-LZW and MC8
MC16
MC32
MC64 improved algorithms is accomplished.It is concluded that MC16 performs well in almost all the datasets with increased data compression ratio of average 13.6% and no time cost.
