In era of cloud computing, data migration is an important issue to minimize cost and time incurred to transmit the data across the network. Data compression is a technique that helps to significantly reduce the transmission time and thus reducing cost. In this paper, a new dictionary-based compression algorithm using bit wise technique has been introduced. The algorithm constitutes two dictionaries, primary dictionary (Static) and secondary dictionary (Dynamic). The data to be transmitted is first divided into chunks of fixed size(16K) and then transmitted after compression along with secondary dictionary. The proposed algorithm will conduce to reduce the number of data packets that needs to be transmitted with better bandwidth utilization thereby augmenting the transmission rate of data.
