Most of the sensor applications collect and analyze sensor data within a given period of time. When sensor send a data to sink, it spend many communication cost. Accordingly, a compression algorithm is one of the most critical issues for the communication cost decrease in sensor fields. In this paper, we propose an algorithm for compressing sensor data using the dynamic bit assignment technique. In our algorithm, sink collect sensor data within a short period of time and make bit assign information. Then sink send the information to sensor. Finally, sensors compresssensing data and send to sink.
