In other to increase the accuracy of the context awareness, temporary storage and utilization for the sensing data were proposed. The criteria to judge whether to use or not the sensing data reported from the sensor in the next time zones was presented by saving it temporarily, the data proved to be used in the next time zones should be recycled. On using by calling the basic probability assignment saved, weights corresponding to the increment of the previous and present time zones should be added. Since then, the belief and uncertainty were calculated by using each focal element's BPA and through this, advanced information can be deduced rather than obtaining context information.
