Abstract Internet of Things (IoT) has posed new requirements to the underlying processing architecture, specially for real-time applications, such as event-detection services. Complex Event Processing (CEP) engines provide a powerful tool implement these Fog computing raised solution support IoT in contrast Cloud-based approach. This work is aimed at analysing CEP-based architecture applications that uses publish-subscribe protocol. A testbed been developed with low-cost and local resources...

New master’s degrees in computer engineering, designed according to Spanish government requirements, include both technical and business subjects provide advanced knowledge compared undergraduate studies. In spite of acquiring this knowledge, our students are not always aware the significant added value positive elements degree provides for their future professional careers. Moreover, we have observed that regard different as isolated blocks knowledge. To tackle these problems, carried out a...

We propose a flow control algorithm for k-ary n-cube networks which avoids the deadlock problems without using virtual channels. Some basic definitions and theorems are proposed in order to establish necessary sufficient conditions verify that an is deadlock-free. Our proposal based on restriction of cut-through rather than routing it can be applied both over central buffers or edge buffers. A minimum free buffer space two packets required. The implementation complexity router according...

Nowadays, the fog computing paradigm is being consolidated as a solution for processing explosion of data generated by lots common IoT devices connected to Internet. In contrast cloud computing, achieves efficient without incurring large latencies or transfers to/from cloud. The distributed nature makes resource orchestration challenge. Commonly used centralized solutions are limited utility in this context. Moreover, nodes usually constrained, so implementation management modules should be...

Grid technologies are emerging as the next generation of distributed computing, allowing aggregation resources that geographically across different locations. However, these independent and managed separately by various organizations with policies. This will have a major impact to users who submit their jobs Grid, they deal issues such policy heterogeneity, security fault tolerance. Moreover, changes conditions, may become unavailable for period time due maintenance and/or suffer failures,...

Fog computing arises as a complement to cloud where and storage are provided in decentralized way rather than the centralized approach of paradigm. In addition, blockchain provides immutable ledger which can provide support for running arbitrary logic thanks smart contracts. These facts lead harness contracts on basis decentralized, autonomous, resilient orchestrator resources fog. However, potentially vast amount geographically distributed fog nodes may threaten feasibility orchestration....

Grid computing involves the coordinated use of disperse heterogeneous resources. This heterogeneity and dispersion makes Quality Service (QoS) still an open issue requiring attention from research community. One way contributing to provision QoS in Grids is by performing meta-scheduling jobs advance, that is, resource where a job will be executed decided some time before are actually executed. But this scheduling needs do predictions about future status resources, including network. The main...

In highly heterogeneous and distributed systems, like Grids, it is rather difficult to provide QoS the users. As reservations of resources may not always be possible, another possible way enhancing perceived by performing meta-scheduling jobs in advance, where are scheduled some time before they actually executed. Thank this, more likely that appropriate available execute job when needed. When using this type scheduling, fragmentation appears become cause poor resource utilization. Because...

Grid technologies have enabled the aggregation of geographically distributed resources, in context a particular application. The network remains an important requirement for any application, as entities involved system (such users, services, and data) need to communicate with each other over network. performance must therefore be considered when carrying out tasks such scheduling, migration or monitoring jobs. Surprisingly, many existing QoS efforts ignore focus instead on processor workload...

Abstract Information and communication technologies backbone of a smart city is an Internet Things (IoT) application that combines such as low power IoT networks, device management, analytics or event stream processing. Hence, designing efficient architecture for real-time applications brings technical challenges include the integration network protocols data In this context, system scalability two architectures has been analysed: first architecture, named POST integrates hyper text transfer...

Summary Fog computing has become a complementary technology to cloud and addresses some of the threats such as response time network bandwidth demand. successes processing data storing near edge, usually is combined with container virtualization provide hardware isolation. Empowered by these capabilities, numerous Internet Things (IoT) applications are developed virtualized instances on resource‐constrained fog nodes single‐board computers (SBC). In addition, blockchain emerged key that...

In Spain, quantity surveyors are entitled to carry out official cadastral surveys, attestations, and certificate issuing according a well-defined professional code. The Official Associations of Quantity Surveyors Technical Architects (COAATs) responsible for endorsing the documentation related actions performed on buildings. An e-platform that enables immutability, traceability, unique property record among all Spanish COAATs, with an affordable cost, is essential streamline involved processes.

The provision of Quality Service in Grid environments is still an open issue that needs attention from the research community. One way contributing to QoS Grids by performing meta-scheduling jobs advance, is, are scheduled some time before they actually executed. In this way, aproppriate resources will be available run job when needed, so requirements (i.e., deadline) met. This paper presents two new techniques, implemented over red-black tree data structure, manage idle/busy periods...

Abstract Objectives The aim of this study was to describe the most common drug-related problems (DRPs) found after discharge, pharmacist interventions and their results for patients enrolled on CONSULTENOS programme. Methods An observational, prospective, multicentre conducted evaluate a pharmaceutical care programme at discharge. Patients from 10 hospitals participating in were enrolled. Pharmacists conducting newly graduated worked under supervision pharmacy staff member; only two...
