Comparative Study on Data Compression Algorithm For Wireless Sensor Network

Data compression techniques are emerging trends in sensor networks. It is an art of compact information. It is used to decrease the amount of data transmitted by source node. It contains Data generating and sink node. Data generating nodes acts as the encoding instruction and sink node act as decoding instruction. In this paper, a loss less dictionary based data compression technique has been proposed which is based on the optimality of LZW code
