Conference Paper
Anomaly detection is increasingly important to handle the amount of sensor data in Edge and Fog environments, Smart Cities, as well as in Industry 4.0. To ensure good results, the utilized ML models need to be updated periodically to adapt to seasonal changes and concept drifts in the sensor data. Although the increasing resource availability at th...

The wide adoption of the recently coined fog and edge computing paradigms alongside conventional cloud computing creates a novel scenario, known as the cloud continuum, where services may benefit from the overall set of resources to optimize their execution. To operate successfully, such a cloud continuum scenario demands for novel management strat...

In this paper we introduce our vision of a Cognitive Computing Continuum to address the changing IT service provisioning towards a distributed, opportunistic, self-managed collaboration between heterogeneous devices outside the traditional data center boundaries. The focal point of this continuum are cognitive devices, which have to make decisions...
Article
The penetration of connected devices in today’s society has reached overwhelming figures particularly in the last decade. At present connected devices are not only becoming available everywhere, but they are rapidly gaining complexity in terms of their ability to hold significant compute and storage capacities. Thus, computing ceases to be confined...
Conference Paper
Fog computing brings cloud computing capabilities closer to the end-devices and users, while enabling location-dependent resource allocation, low latency services, and extending significantly the IoT services portfolio as well as market and business opportunities in the cloud and IoT sectors. With the number of devices growing exponentially globall...

Article
Coordinated fog (edge) and cloud computing systems are expected to expedite the evolution of smart farming toward openness and data sharing while making agriculture economically sustainable for smaller farms. We demonstrate a farming system that deploys low-cost technology and uniquely considers animal welfare and quality of life.
Conference Paper
Over the course of the last decades there has been significant growth in smartphone penetration and capacities. This trend presently complements the rise of IoT and ever complex and smarter connected devices. On balance, considerable contribution has been made to the emergence of unprecedented computing capacity at the edge of the network, which is...

Serverless computing has become very popular today since it largely simplifies cloud programming. Developers do not need to longer worry about provisioning or operating servers, and they pay only for the compute resources used when their code is run. This new cloud paradigm suits well for many applications, and researchers have already begun invest...
Conference Paper
Full-text available
several efforts are currently active in dealing with scenarios combining fog, cloud computing, out of which a significant proportion is devoted to control, and manage the resulting scenario. Certainly, although many challenging aspects must be considered towards the design of an efficient management solution, it is with no doubt that whatever the s...
Preprint
With the development of new system solutions that integrate traditional cloud computing with the edge/fog computing paradigm, dynamic optimization of service execution has become a challenge due to the edge computing resources being more distributed and dynamic. How to optimize the execution to provide Quality of Service (QoS) in edge computing dep...
Article
Cloud computing emerged as a centralised paradigm that made “infinite” computing resources available on demand. Nevertheless, the ever-increasing computing capacities present on smart connected things and devices calls for the decentralisation of Cloud computing to avoid unnecessary latencies and fully exploit accessible computing capacities at the...
Conference Paper
Fog computing enables location dependent resource allocation and low latency services, while fostering novel market and business opportunities in the cloud sector. Aligned to this trend, we refer to Fog-to-cloud (F2C) computing system as a new pool of resources, set into a layered and hierarchical model, intended to ease the entire fog and cloud re...

Edge environments offer a number of advantages for software developers including the ability to create services which can offer lower latency, better privacy, and reduced operational costs than traditional cloud hosted services. However large technical challenges exist, which prevent developers from utilising the Edge; complexities related to the h...
Article
The Internet of Things (IoT) has empowered the development of a plethora of new services, fueled by the deployment of devices located at the edge, providing multiple capabilities in terms of connectivity as well as in data collection and processing. With the inception of the Fog Computing paradigm, aimed at diminishing the distance between edge-dev...
Chapter
The advent of fog computing devices as computing paradigm enriching traditional cloud computing applications, paves the way to deploy innovative services, typically not completely appropriate and well supported by cloud computing technology. For example, fog computing is highly suitable for services requiring high constraints on delay, such as depe...
Conference Paper
The BASMATI architecture is designed to improve the service quality perceived by end-users. In particular, it focuses on the support of applications that offer services to mobile end-users, ranging from those crossing national borders to those roaming around locally and who both need access to widely dispersed cloud resources. To achieve this, the...

Platform-as-a-Service (PaaS) is the Cloud area concentrating the major growth in the last years in terms of adoption and market share. At the same time Cloud models are evolving towards Hybrid Clouds through the consideration of service expansion across a diversity of Cloud offerings. So far, the majority of multi-cloud approaches have explored Iaa...

Although mobile devices became more powerful and sophisticated over the last decade, enabling rich-multimedia services, resource constraints still hinder today’s mobile applications from reaching their potential. In this context, cloud environments are considered to be the enabling technology for a broad set of scenarios and applications. Clouds ca...

The cloud based delivery model for IT resources is revolutionizing the IT industry. Despite the marketing hype around “the cloud”, the paradigm itself is in a critical transition state from the laboratories to mass market. Many technical and business aspects of cloud computing need to mature before it is widely adopted for corporate use. For exampl...
