Title
Operating Mode Optimization for Nodes of Data Supply Chain.
Abstract
E-Health Systems are transforming the whole healthcare process to become more efficient and less expensive. QoS is usually used as a key criterion for E-Health service. The study shows that QoS of data supply chain are highly related to operating mode of nodes. However, existing optimization methods seldom took this observation into account, which shall decrease the optimal performance. In this paper, we propose an operating mode optimization strategy for nodes of data supply chain environments including E-Health Systems. First, a QoS mathematical model is developed. Then, we put forward the objective function to balance the data freshness, hit rate and cost from the aspects of users and service providers. To this end, we present a novel operating mode selection algorithm. It selects appropriate candidate operating modes for each node when generating composite operating mode of nodes with optimal QoS values. Experimental results indicate that the effectiveness of the proposed approach outperforms the existing methods by at least 20%.
