—Cloud computing offers customers an efficient way to flexibly allocate resources to meet demands. Cloud service vendors can offer consumers three purchasing plans, i.e., on-demand, spot, and reserved instances for resource provisioning. Since price of resources in reservation plan is generally cheaper than that in on-demand plan, in this study we attempt(More)
—Time-triggered communication protocols, such as Time-Triggered Protocol (TTP) and FlexRay, have potential to solve many system integration and concurrent engineering issues in the aerospace industry. This paper investigates the scheduling of periodic applications on time-triggered systems. A novel scheduling problem is formulated to capture a unique(More)
—As time-triggered communication protocols (e.g., TTCAN, TTP, and FlexRay) are widely used on vehicles, the scheduling of tasks and messages on in-vehicle networks becomes a critical issue for offering quality-of-service (QoS) guarantees to time-critical applications on vehicles. This paper studies a holistic scheduling problem for handling real-time(More)
The Cloud with its abundant on-demand processor, storage, and bandwidth capacities and the elastic billing models has been emerging as a promising platform to scientific workflow computations. However, in reality, due to ineffective use of or practical constraints on the provisioned resources, the best-effort model to allocate as many as possible resources(More)
