Towards cost efficient mobile service and information management in ubiquitous environment with cloud resource scheduling

Highlights：

• We study the service instance selection problem in the cloud environment. We aim to deploy persistent service for the wide-area users over the long-run.

• We present a new QoS model.

• We classify the problem into three cases. We present algorithms for all the cases, and evaluate the performance of the proposed algorithms via extensive simulations.

• The simulation results show that our algorithms have a significant efficiency on service response time reduction.
