Vulnerability identification has been broadly studied as a way to improve cybersecurity. Internet of Things (IoT) ecosystems are considered particularly vulnerable as a whole, due to their widespread deployment, low processing ability, difficulty ...

A control flow graph (CFG) is a type of directed graph that shows the execution paths of the programs. It is a mathematical structure that is actively used in software testing. It can be constructed from the source or the executable of the ...

Real-time and safety-critical systems are an integration of multiple functionalities onto a single computing platform. Some of the functionalities are safety-critical and subject to certification while the rest of the functionalities are nonsafety-...

Recommender systems appeared in the early 90s to help users deal with cognitive overload brought by the internet. From there to now, such systems have assumed many other roles like help users to explore, improve decision making, or even entertain. ...

Fog computing is becoming a popular paradigm for bringing the advantages of the cloud nearer to the network edge. This way, computational tasks can be offloaded from end devices to nearby fog nodes, thus benefiting from high computational power ...

Topology and Orchestration Specification for Cloud Applications (TOSCA) is an OASIS standard for specifying the topology of cloud applications, their deployment on physical or virtual cloud resources, and their orchestration. In recent years, the ...

Wireless sensor networks are commonly used to collect observations of real-world phenomena at regular time intervals. Sensor nodes rely on limited power sources, and some studies indicate that the main source of energy consumption is related to ...

Three-dimensional (3D) NAND flash memory-based solid state drives (SSDs) have been widely adopted in cyber-physical systems, due to its performance benefits and scalability. Although 3D flash rapidly increases storage capacity by ...

We analyzed the performance of a multi-node OpenStack cloud amid different types of controlled and self-induced network errors between controller and compute-nodes on the control plane network. These errors included limited bandwidth, delays and packet ...

The cloud brings new possibilities to run traditional HPC applications, giving its flexibility and reduced cost. However, running MPI applications in the cloud can reduce appreciably its performance, because the cloud hides its internal network topology ...

Data centers are major contributors to the emission of carbon dioxide to the atmosphere, and this contribution is expected to increase in the following years. This has encouraged the development of techniques to reduce the energy consumption and the ...

One of the core principles in service oriented computing is that services are always on and available. There are however domains where running services all the time is not suitable, for example when applying simulation workflows in the eScience domain. ...

As the organizations are shifting their workload on cloud computing, the demand of cloud services has increased tremendously. With the increased usage of cloud data centers, there is huge consumption of energy (power and heat), contributing to high ...

High availability in cloud computing services is essential for maintaining customer confidence and avoiding revenue losses due to SLA violation penalties. Since the software and hardware components of cloud infrastructures may have limited reliability, ...
