An Embedded Cloud Database Service Method for Distributed Industry Monitoring

Current client/server or multiagent based embedded database systems are hard to match the quality of service of distributed industry monitoring. To address the issues, an embedded cloud database service (ECDBS) method is proposed. First, an ECDBS framework is constructed, and a dual-timing transaction control ((DTC)-C-2) method is proposed to increase the real-time performance and stableness of transaction processing. Then, a cloud computing middleware subsystem is developed to perform dynamical device management and real-time DB query, and a distributed network sniff-timing scheduling (DNS2) algorithm is proposed to improve the efficiency of ECDBS system. Finally, the numerical/industrial experiment results showthat the DT(2)Cmethod can improve the real-time performance of transaction processing in a condition that guaranteed the accessing stability, and the data transfer rate can reach more than 20 MB/s; the DNS2 algorithm can perform the better throughput and time delay, and decrease the power consumption; compared with the MySQL and Berkeley DB, the total transaction processing time can decrease 45.5% and 36.7%, respectively.
