In this paper we consider the problem of filming sport events, ensuring high quality image transmission to the spectators. A fleet of drones is used to cover the area in which the play takes place and to track all events. Auxiliary drones are used to support filming drones in order to transmit high quality image to the disadvantaged spectators with respect to the event that takes place in a certain...
Software Defined Networking (SDN) is a new networking paradigm which provides better decoupling between control plane and data plane. The separation not only allows OpenFlow (OF) switches in the data plane simply to forward data, but also enables the centralized programmable controller to control the behavior of entire network. SDN makes it possible to manage the network more flexible and simple....
The idea of controller performance assessment is becoming very important in the process control area. One of the main performance monitoring index is based on the minimum variance control benchmark proposed by Harris. However, the low value of this index means only low performance of the controller. So, it is difficult to tune the controlled parameters based on this index. This paper considers the...
Environmental emergencies early warning and response, such as floods, forest fires, volcanic eruptions, etc., are one of the areas where space information can be very useful. For this reason the Argentinean Space Plan includes a chapter, called Space Information Cycle, completely dedicated to emergencies. In this framework, CONAE, the Argentinean Space Agency has a work team specifically aimed at...
User data has become a backbone of today's ICT services and applications, where various providers compete to provide better services to their users based on a personalized content. However, user data is simultaneously becoming a tempting target for malicious individuals who try to get the data and exploit it for their own financial gain. The necessity for high-quality data loss prevention is obvious...
The emergence of many heterogeneous sensor systems on the Web has produced huge amounts of sensor data. This requires building the customized and automated processing methods, which can be formed by connecting the services on the Web. Based on the semantic Web services markup language named OWL-S, the algorithms for processing sensor data on the Web are represented as the service ontologies and become...
Coverage is a primary metric for ensuring the quality of services provided by a wireless sensor network (WSN). In this paper, we focus on the $k$-coverage problem, which requires a selection of a minimum subset of nodes among the deployed ones such that each point in the target region is covered by at least $k$ nodes. We present both centralized and distributed protocols to tackle this fundamental...
Internet, combined with the technologies of communication and information (ICT), is changing the society. Most aspects of the life of each individual have been influenced by this technological revolution. Education is not indifferent to this reality, since a number of tools and applications have been created which seek to improve the learning process. However, these educational technologies do not...
In this paper we study the problem of estimating the cardinality of pairwise set operations (union and intersection) over sets possessed by different data owners, while preserving differential privacy. In our problem setting, a data owner could only communicate with an untrusted server, and thus have to perturb its set data for privacy protection before sharing them with the server. This problem setting...
In order to adapt to the narrow space and complex branch in deep mine roadway, which have an adverse impact on the accuracy of nodes localization, a self-localization algorithm for deep mine wireless sensor networks based on MDS-MDS and rigid subset (Rigid-MDS) was proposed. The new distributed algorithm divides whole network into some globally rigid subset based on rigid graph theory, in which nodes...
Cloud Service Broker federates multiple Cloud Service Providers into a single entity to customers. The benefits that can be enjoyed by Cloud Service Consumer are flexibility, ease of use, and reduced cost. However, because of the unique properties and configurations of each cloud provider, sometime it's not easy to migrate between one cloud provider to another. Furthermore, the advantage of using...
Before inception of Internet of Things (IoT), personal computers and laptop were used to handle daily tasks of individuals like mail surfing, access to bank portal, observing current temperature, among others. Nowadays, IoT-enabled smart devices like smart mobile phones, PDAs, and tablets are being used by them for such tasks due to rapid growth in IoT. Smart homes have been widely accepted by individuals...
Computer programming courses require a lot of practice. Nevertheless, the difficulties found when trying to install the computer programming environment used in the university courses prevent many students from practicing at home. Hence, they can only practice during the computer laboratory lessons, or when the laboratories are available for the students. This limitation negatively affects the learning...
Conserving energy at home is a personal choice, but when multiplied by the conserving efforts of tens of millions of homeowners, it can reduce our energy demands and increase our long-term quality of life. The Objective of the project is to drive awareness and conservation of the worlds natural re-sources through compelling analytics and targeted, actionable conservation recommendations. Synergy is...
In the handling of the nonlinear systems, Kernel Ridge Regression (KRR) has recently served as an effective method to deal with multicollinearity problem, but it has not been used to solve the problem of fault diagnosis problems. KRR is unable to ensure the safety and the reliability of industrial systems. While previous fault detection method still encounters some problems for key performance indicator...
Software-Defined Networks (SDN) are constantly evolving and so is their software. One of the key advantages of SDN over traditional networks is the ability to rapidly develop and deploy new features. However, updating them often requires restarting the SDN controller and causes network downtime. In addition to such planned updates, unforeseen, accidental downtime is also a risk for SDN networks. While...
Our work aims at helping teachers to monitor learners' engagement during mind mapping activities. The use of mind maps helps students to elaborate cognitive learning strategies like creating and organizing contents. To assess the quality of these mind maps, teachers need tools to understand students' choices and strategies when constructing their mind maps. We have defined in collaboration with teachers...
Medical sensors are usually attached to or implanted inside patient body. Since medical diagnosis and treatment are a complicated procedure, multiple sensors in Body Area Networks (BAN) often need to form a group to share the measurements during the decision making procedures. To protect the confidentiality and integrity of exchanged data, group keys need to be established and distributed. In this...
Digital documents are likely to have problems associated with the persistence of links, especially when dealing with references to external resources. People keep track of various webpages of their interest using distributed digital collections and without possession of these documents; the curator cannot control how they change. In the current context, managing these distributed digital collections...
