| Abstract(in English) | To provide persitence for sensor data streams, we have proposed the Light-Neighbor-WAL(L-WAL) and the Temporal Consistency Conscious-WAL(T-WAL). We have acquired the result that the T-WAL is superior to the L-WAL in the sense of appending time, however it is inferior to the L-WAL in the sense of the freshness of data. This would be incurred by the scheduling policy of transactions that is not conscious to the freshness of data. In this paper, we propose a new scheduling algorithm that considers both freshness of data and response time. The proposed policy would enhance the freshness of data and the response time by notifying monitored sensor data streams to the scheduler. |
