Equipped with easy-to-access micro computation access points, the fog computing architecture provides low-latency and ubiquitously available computation offloading services to many simple and cheap Internet of Things devices with limited computing and energy resources. One obstacle, however, is how to seamlessly hand over mobile IoT devices among different computation access points when computation...
The utilization of cloud computing resources contributes to a fast growth of e-business and e-government where businesses and government agencies often require processing a large volume of service requests in a constrained period of time. In order to achieve on-time completion of a large volume of time-constrained parallel processes, this paper proposes a novel dynamic checkpoint selection strategy...
This paper proposes an improved particle swarm optimization (PSO) algorithm to solve the sensor configuring optimization problem for the harmonic monitoring in the power grid. The model of the tested and un-tested node voltage and current is firstly set up. Then the PSO algorithm, which uses the logistic chaos method to obtain the initialized value for a better ergodic property and normalizes the...
Today, Cloud Computing and the Internet of things are two “major forces” that drive the development of new Information Technology (IT) solutions. Many Internet of things (IoT) based large-scale applications rely on a cloud platform for data processing and storage. However, big data generated or collected by large-scale geo-distributed devices needs to be transferred to the cloud, often becoming a...
Nowadays, most business processes are running in a parallel, distributed and time-constrained manner. How to guarantee their on-time completion is a challenging issue. In the past few years, temporal checkpoint selection which selects a subset of workflow activities for verification of temporal consistency has been proved to be very successful in monitoring single, complex and large size scientific...
Due to the dynamic nature of cloud computing, how to achieve satisfactory QoS (Quality of Service) in cloud workflow systems becomes a challenge. Meanwhile, since QoS requirements have many dimensions, a unified system design for different QoS management components is required to reduce the system complexity and software development cost. Therefore, this paper proposes a generic QoS framework for...
