The efforts and findings of the last decades of research on the formalization and the verification of Web services have given a certain level of assurance on Web services. However new challenges such as high availability and security issues are not fully addressed. In fact, Web services are exposed to attacks that appear continuously. These issues have naturally paved the way to a new research topic...
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...
Cloud computing represents a disruptive innovation in the way of provisioning and managing IT and network resources. One of the main challenge of this paradigm is the monitoring of the actual services performance offered by different Cloud service providers. For this reason, service level management plays a central role to ensure the quality of services in Public Cloud and requires a structured approach...
To meet the communication expectations of the future, mobile networks need to evolve quicker than ever toward systems with ultra-low latency, huge traffic volume and higher data rates. Cloud-enabled radio systems have been introduced as a promising solution to meet these demands with the help of network functions virtualization techniques and network edge processing capabilities, which allow for increased...
Cloud federation is an emergent cloud-computing paradigm where partner organisations share data and services hosted on their own cloud platforms. In this context, it is crucial to enforce access control policies that satisfy data protection and privacy requirements of partner organisations. However, due to the distributed nature of cloud federations, the access control system alone does not guarantee...
Nowadays, more and more enterprises and research institutes choose to build mini-datacenters and deploy private cloud environments to meet growing business and research needs. To make users can run different application frameworks on the same datacenter, Cao et al. [5] proposed a new service model named ClaaS (Cluster as a Service) and developed a lightweight prototype system named Docklet which is...
SaaS based cloud computing promises to provide dedicated and specialized computational resources on-premise and on a pay-per-use base to cloud consumers. These benefits, however, are traded with data confidentiality concerns: once data is transmitted to a cloud service, cloud consumers loose control over their data and remain in uncertainty about how their data is processed and disseminated inside...
With the growth of Infrastructure as a Service (IaaS) in cloud computing, and the Internet of Things (IoT), network monitoring of the global infrastructure will continue to expand, as cybersecurity will become of primary importance. Current network monitoring approaches, particularly those that are agent-based, are proprietary, costly, and may not scale. This paper proposes a lightweight, scalable...
Electrical Grid we have is more than 50 years old. The integration of information technology to the electric grid system is expected to address many shortcomings of the current and traditional electrical grids that have resulted in Smart Grid which is gaining lot of interest and momentum. In Smart Grid, Power Distribution is one part which requires monitoring and control. Lot of technologies and have...
While many institutions, whether industrial, academic, or governmental, satisfy their computing needs through public cloud providers, many others still manage their own resources, often as geographically distributed datacenters. Spare capacity from these geographically distributed datacenters could be offered to others, provided there were a mechanism to discover, and then request these resources...
In the context of demographic ageing the Ambient Assisted Living is a priority approach in healthcare for elderly, with health monitoring (HM) as a central activity. The Cloud-IoT architecture integrates cloud computing and Internet of Things technologies to highlight the advantages derived from their complementarities. The sensing service is aimed at improving the sensor data accessibility and usage...
Bees are an important part of our echo system. Pollinators, such as bees, help at least 30% of the worlds crops and 90% of the worlds wild plans to thrive via cross-pollination. Studies show that between 2015 and 2016 beekeepers lost 44% of bee colonies over the winter, this is up about 10% from the previous decade. Causes for this decline is correlated to the overall hive health. The healthier the...
Hypertension is a chronic disease characterized by high blood pressure levels. Lack of adherence to the treatment of hypertension is a growing concern among health professionals. For this, m-Health solutions are increasingly evident, since they can automate processes and facilitate the inclusion of the patient's health conditions in a practical way and in any place, allowing the health professional...
Software aging is a cumulative process which can lead long-running systems to failures. Software rejuvenation is the countermeasure of software aging. Rejuvenation actions usually comprise system reboot or application restart. Software aging appears as a significant concern for the reliability of software systems. Therefore, techniques and methods to analyze software aging and rejuvenation are of...
Cloud storage usages are becoming increasingly popular on mobile devices. Through an extensive motivation study, we find that cloud storage accesses from mobile apps suffer from several notable problems that undermine usage experiences. The root cause is that the way of cloud storage providers deploying their services onto mobile devices relies on app developers for the correct and appropriate implementations...
There has been a prolific rise in the popularityof cloud storage in recent years. While cloud storage offersmany advantages such as flexibility and convenience, users arenow unable to tell or control the actual locations of their data. This limitation may affect users' confidence and trust in thestorage provider, or even be unsuitable for storing data withstrict location requirements. To address this...
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...
Identifying anomalous events in the network is one of the vital functions in enterprises, ISPs, and datacenters to protect the internal resources. With its importance, there has been a substantial body of work for network anomaly detection using supervised and unsupervised machine learning techniques with their own strengths and weaknesses. In this work, we take advantage of the both worlds of unsupervised...
Micro-clouds infrastructures allow supporting applications on local and energy-efficient resources. Communication between micro-clouds takes place on shared and non-dedicated Internet links. Network control and optimization can only happen at the edge. For availability and persistence, the storage of application data must be geo-replicated. Maintaining strong data consistency under concurrent accesses...
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...
