Many Cyber-Physical Systems (CPS) at different scales are being developed for a variety of applications that provide valuable interactions between the cyber world and the physical systems and environments. However, the development of these systems face many challenges due to the complexity of the applications. An appropriate middleware is needed to provide infrastructural support and assist the development...
Applications integrating software with a large number of physical objects and devices in a large-scale Internet of Things (IoT) networks are on the rise. Some examples of these applications are smart grids and water networks and intelligent transportation systems. As they operate in and control a large heterogeneous environment, these applications need real-time controls, powerful and scalable data...
The goal of this paper is to provide a holistic overview and identify challenges of reliability modeling in Cyber-Physical Systems (CPS). Cyber-physical systems are complex systems that incorporate three paradigms of different natures: hardware, software and humans. Each of the paradigms raises its specific challenges and instills its own types of faults and failures that occur following their specific...
Cyber-physical systems are slowly emerging to dominate our world. Cyber-physical systems (CPS) are systems that tightly integrates users, devices and software. Whereas many of these systems are obviously safety-critical systems, some of them become so under special circumstances. This is the case with our focus CPS, i.e. building management systems (BMS), which are not always safety critical per se,...
Middleware can provide novel and practical approaches for enhancing Cyber-Physical Systems (CPS) application development processes and operations. This paper discusses the roles and advantages of using middleware to build CPS. In addition, the paper studies the required features needed in such middleware for development and operation of CPS.
Cyber-Physical Systems (CPS) provide many smart features for enhancing physical processes. These systems are designed with a set of distributed hardware, software, and network components that are embedded in physical systems and environments or attached to humans. Together they function seamlessly to offer specific functionalities or features that help enhance human lives, operations or environments...
A Linear Wireless Sensors Network (LSN) is a sensor network model used for monitoring linear structures such as oil, gas, and water pipelines. This type of network depends on the information sent from one node to another in a sequence. As a result, a failure or attack that occurs at any node may isolate some nodes from the network, which will affect the reliability of the entire network. In this situation,...
Underwater Acoustic Sensor Networks (UASNs) can be used to monitor long underwater pipeline structures for oil, gas, and water. In this case, a special type of UASNs, UASN-P (UASN for long pipelines) is used. One of the main challenges of using UASN-P is the reliability of the connections among the nodes. Faults in a few contiguous nodes may cause the creation of holes which will result in dividing...
Linear Wireless Sensor networks (LSN) are used to monitor long linear critical structures such as pipelines, rivers, railroads, international borders, and high power transmission cables. Due to the importance of these structures, the LSN must be designed with high reliability considerations. However, one of the main challenges of LSN design is the connection reliability among the nodes. Unlike in...
