Web21 feb. 2024 · The best algorithm that is of lossless nature for wireless sensor networks is that of S-LWZ. This has been widely used in the compression of data so that the transmission of the data cannot bring constraints to the network(Ziv & Lempel 1977). The S-LWZ algorithm has been developed from LWZ algorithm which has been used popular … WebLZW data compression algorithm is popular for data compression because it is an adaptive algorithm and achieves an excellent compromise between compression performance and speed of execution. LZW is a dictionary based data compression algorithm, which compress the data in a lossless manner so that no information is lost.
