This paper presents the edge intelligence supportfor smart IoT using the service-oriented architecture. InIoT, there are many sensors deployed for different purposes. Sensors of different modalities must be integrated and theircharacteristics analyzed to enhance the system intelligence. Inthis paper, we present the edge computing framework in the WuKong-based IoT architecture. WuKong is an IoT middlewarethat...
Internet of Things (IoT) services are becoming a popular class of services. Compared to traditional pure software-based services, IoT services are deployed on and constrained by devices in physical environments. Interruption of an IoT service may be caused by energy failure of its host device. Balancing energy consumption of all devices in outdoor settings is desirable to maximize the system lifetime...
In this work, we extend WuKong middleware to interface with context engine, to learn the context based on the history of user behaviors, and to command the devices in the system according to the context. With the enhanced WuKong framework, one can design and implement context-ware/user-behavior-aware IoT applications using FBP in WuKong middleware.
To prolong the IoT system lifetime, a system should minimize the energy comsumption on devices. The RF communication energy cost is dependent on the communication distance. This paper presents a communication distance aware methodology for mapping and deploying IoT applications on sensor devices in a physical environment. Given a flow-based service process, WuKong will select and set up the most efficient...
Systems built for future Internet of Things (IoT) may have a large number of intelligent objects with sensing, actuating, and computing capabilities. In a specific context, a smart application deployed in the system needs to meet QoS requirement in order to provide a good experience for users. The Woking middleware use service oriented paradigm to help application developers define the logical functionalities...
This paper presents an energy sentient methodology for mapping and deploying IoT applications on sensor devices installed in a target environment. The deployment decision support is part of the WuKong intelligent middleware which is designed to automatically discover and manage smart sensor devices. Given a pre-defined flow-based service process, WuKong will select and set up the most efficient configuration...
To facilitate computing resources commercialization and to encourage more users to participate in the trading, we propose a computing resource market model CR-Market in this paper. Compared with existing Grid and Cloud markets, CR-Market has the following distinctive features: (1) Its architecture is based on the combination of Grid and Cloud. Market participants include buyers and sellers of Cloud...
Many SOA applications are now migrating to cloud servers, due to cloud's low cost provision, elasticity for growth, and better availability. Although cloud service providers have implemented reliable management system for their infrastructure, hybrid cloud users often lack easy monitoring and diagnosis facilities to discover the root cause of end-to-end QoS violations. However, the cause must be identified...
Service flow in SOA systems need to detect quality of service (QoS) problems and to guarantee end-to-end performance. In previous work, we have proposed two faulty service identification methods: a dependency matrix based diagnosis and a Bayesian network based diagnosis. In this paper, we present a hybrid diagnosis to achieve high diagnosis accuracy and low diagnosis cost. The hybrid diagnosis reduces...
Automatic service composition has been an active research area in the field of service computing. Service engineers demand algorithms that not only synthesize the correct work plans but also meet the need of the overall qualities like response time, throughput, fee, etc. In this paper, we present a novel QoS-aware approach which adopts a two-phase graph search algorithm. This approach effectively...
With the proliferation of Web services, service engineers demand good automatic service composition algorithms that not only synthesize the correct work plans from thousands of services but also satisfy the quality requirements of the users. Our observation is that conventional approaches suffer from serious limitations in scalability and accuracy when addressing both requirements simultaneously....
Automatic service composition has been a hot topic in both academia and industry. It begins with syntactic composition, and then evolves semantic description. QoS of the composition comes into researcherspsila mind, which aims at meeting the need of the overall qualities like service fee, response time, throughput, etc. In this paper, a novel QoS-aware approach is presented. It adopts a forward filtering...
The large deflection dynamic plastic response of fully clamped square plates with stiffeners under blast load is analyzed. Various relevant motion patterns and criterions are presented. The formulas of maximum permanent deformation of the plates with stiffeners are derived.
