Modern mechanical engineering systems are primarily designed to perform a specific system process in an optimal manner. For this purpose, they use control systems that monitor and influence the process with the help of sensors and actuators. Changing control values or (physical) disturbances are recorded and considered by the control systems. Problems arise whenever the disturbances are not physical,...
Internet of things (IoT) is a smart technology that connects anything anywhere at any time. Such ubiquitous nature of IoT is responsible for draining out energy from its resources. Therefore, the energy efficiency of IoT resources has emerged as a major research issue. In this paper, an energy-efficien t architecture for IoT has been proposed, which consists of three layers, namely, sensing and control,...
Internet of Things is the new revolution that is going to impact every facet of our lives. Internet of Things (IoT) is the new technology which includes the collection of Sensors, Actuators, processors and other development boards (eg. Raspberry pi, Arduino etc) to collect the data from different sources depending upon domain of application, process the acquired data before sending to distant cloud...
Deploying composite applications to Fog nodes in a QoS-and context-aware manner is challenging due to the heterogeneity and scale of Fog infrastructures. Application components must be provided with the software and hardware capabilities they need. Communication links that support interactions between components must meet certain QoS (latency and bandwidth). On the other hand, different Fog and Cloud...
The paper presents an example Sensor-cloud architecture that integrates security as its native ingredient. It is based on the multi-layer client-server model with separation of physical and virtual instances of sensors, gateways, application servers and data storage. It proposes the application of virtualised sensor nodes as a prerequisite for increasing security, privacy, reliability and data protection...
Cyber-physical Systems (CPS) have components deployed both in the physical world, and in computing environments, such as smart buildings or factories. Elastic Cyber-physical Systems (eCPS) are adaptable CPS capable of aligning their resources, cost, and quality to varying demand. However, failures can appear at run-time in the physical or software resources used by the eCPS. Failures can have different...
The Internet of Things (IoT), which has had an unprecedented effect in the manufacturing industry, is now becoming increasingly popular in everyday life. Even with the rising interest in IoT among developers, there is no simple way for them to prototype and realize their ideas. As of today, developing an IoT project requires cross domain knowledge of hardware, embedded systems, communication protocols,...
The use of cloud computing in different application areas is growing fast. More and more functions are being moved into the cloud in order to take advantage of cloud computing strengths such as scalability, resources on demand, and usage based cost models. However, most types of embedded systems are still in an early phase of cloud adoption, with a few exceptions found in e.g., data storage and user...
This paper presents the system architecture of an event-based building management platform. By incorporating the distributed computing technologies in its core, it is able to adaptively scale horizontally without the redesign and the configuration downtime. The commodity hardware and networks used, permit vertical scaling if performance requirements change after the deployment. Additionally, the proposed...
Fault tolerance in cloud computing platforms and applications is a crucial issue. This issue is especially difficult since cloud computing relies by nature on a complex splitting into many layers. From a technical point of view, most cloud computing platforms exploit virtualization, which implies that they are split into 3 layers: hosts, virtual machines and applications. From an administration point...
We take the paradigm of cloud computing developed in the cyber-world and put it into the physical world to create a cyber-physical computing cloud. A server in this cloud moves in space making it a vehicle with physical constraints. Such vehicles also have sensors and actuators elevating mobile sensor networks from a deployment to a service. Possible hosts include cars, planes, people with smartphones,...
In this paper, we present a policy-based framework that supports automated dynamic resource management in a virtualized environment. This allows for flexibility in how resources are allocated. We show how this framework can be used to support memory management through the use of migration and making local resource adjustments.
