Indeed, the embedding of emotional awareness features into virtual learning environments could offer a more authentic and challenging e-Learning experience, either individual or collaborative. However, the lack of empirical results together with the complexity attributed to the management by computers of human emotions and affective data, seriously limits the advances in e-Learning as it impedes to virtualize many real-world learning situations in which emotions play a significant role. In this paper, we investigate the use of the SmartBox device for emotion measurement of distance learners during their study as well as the development of affective strategies based on the SmartBox's stimulation capabilities. The aim is to collect emotion data from different sources in order to provide the most appropriate affective responses that positively influence distance learners' study and results and ultimately enhance the e-Learning process.Peer ReviewedPostprint (author's final draft

Thus, it is important for each peer to have some number of neighbor peers. Moreover, it is more significant to discuss if each peer has reliable neighbor peers. In reality, each peer might be faulty or might send obsolete, even incorrect information to the other peers. We have implemented a P2P platform called JXTA-Orverlay, which defines a set of protocols that standardize how different devices may communicate and collaborate among them. JXTA-Overlay provides a set of basic functionalities, primitives, intended to be as complete as possible to satisfy the needs of most JXTA-based applications. In this paper, we present two fuzzy-based systems (called FPRS1 and FPRS2) to improve the reliability of JXTA-Overlay P2P platform. We make a comparison study between the fuzzy-based reliability systems. Comparing the complexity of FPRS1 and FPRS2, the FPRS2 is more complex than FPRS1. However, it considers also the sustained communication time which makes the platform more reliable.Peer ReviewedPostprint (author's final draft

Using Assistive Technologies in Autism Care Centers to Support Children Develop Communication and Language Skills. A Case Study: Albania

In this paper, we propose the use of the smart environment based on Internet of Things (IoT) and P2P technology as a form of assistive environment in autism care centers to support children develop communication and language skills. We are going to propose the use of the smart environment in Albanian Regional Center for Autism in Tirana, Albania. The smart environment is proposed as an assistive environment for this center in order to support students’ learning during the time that they come to the center for support. Our proposed system uses JXTA-Overlay platform and SmartBox device to monitor the children and create P2P communication between children, caregivers and therapists. Various visual systems, such as objects, photographs, realistic drawings, line drawings, and written words used with assorted modes of technology can support engaged learning and then can increase and maintain the concentration of children with ASD during learning

Design and implementation of testbed using IoT and P2P technologies: improving reliability by a fuzzy-based approach

The internet of things (IoT) is a new type of internet application which enables the objects to be active participants with other members of the network. In P2P systems, each peer has to obtain information of other peers and propagate the information through neighbouring peers. However, in reality, each peer might be faulty or might send incorrect information. In our previous work, we implemented a P2P platform called JXTA-overlay, which provides a set of basic functionalities, primitives, intended to be as complete as possible to satisfy the needs of most JXTA-based applications. In this paper, we present the implementation of a testbed using IoT and P2P technologies. We also present two fuzzy-based systems (FPRS1 and FPRS2) to improve the reliability of the proposed approach. Comparing the complexity of FPRS1 and FPRS2, the FPRS2 is more complex than FPRS1. However, FPRS2 makes the platform more reliable.Peer ReviewedPostprint (author's final draft

A fuzzy-based system for peer reliability in JXTA-overlay P2P considering number of interactions

The trustworthiness of peers is very important for safe communication in P2P system. In this paper, we propose a fuzzy-based reliability system for P2P Communications in JXTA-Overlay. We use three input parameters: Number of Interactions (NOI), Amount of Data Exchanged (ADE), and Reputation (R) and the output is Peer Reliability (PR). We evaluate the proposed system by computer simulations. The simulation results show that the proposed system have a good behaviour can be used successfully to evaluate the scale of reliability of the new peer connected in JXTA-Overlay.Peer ReviewedPostprint (author's final draft

A comparison study for two fuzzy-based systems: improving reliability and security of JXTA-overlay P2P platform

This is a copy of the author's final draft version of an article published in the journal Soft computing.The reliability of peers is very important for safe communication in peer-to-peer (P2P) systems. The reliability of a peer can be evaluated based on the reputation and interactions with other peers to provide different services. However, for deciding the peer reliability there are needed many parameters, which make the problem NP-hard. In this paper, we present two fuzzy-based systems (called FBRS1 and FBRS2) to improve the reliability of JXTA-overlay P2P platform. In FBRS1, we considered three input parameters: number of interactions (NI), security (S), packet loss (PL) to decide the peer reliability (PR). In FBRS2, we considered four input parameters: NI, S, PL and local score to decide the PR. We compare the proposed systems by computer simulations. Comparing the complexity of FBRS1 and FBRS2, the FBRS2 is more complex than FBRS1. However, it also considers the local score, which makes it more reliable than FBRS1.Peer ReviewedPostprint (author's final draft

Improving reliability of JXTA-overlay P2P platform: a comparison study for two fuzzy-based systems

The final publication is available at IOS Press through http://dx.doi.org/10.3233/JHS-150506In P2P systems, each peer has to obtain information of other peers and propagate the information to other peers through neighboring peers. Thus, it is important for each peer to have some number of neighbor peers. Moreover, it is more significant to discuss if each peer has reliable neighbor peers. In reality, each peer might be faulty or might send obsolete, even incorrect information to the other peers. We have implemented a P2P platform called JXTA-Overlay, which defines a set of protocols that standardize how different devices may communicate and collaborate among them. It abstracts a new layer on the top of JXTA through a set of primitive operations and services that are commonly used in JXTA-based applications and provides a set of primitives that can be used by other applications, which will be built on top of the overlay, with complete independence. JXTA-Overlay provides a set of basic functionalities, primitives, intended to be as complete as possible to satisfy the needs of most JXTA-based applications. In this paper, we present two fuzzy-based systems (called FRS1 and FRS2) to improve the reliability of JXTA-Overlay P2P platform. We make a comparison study between the fuzzy-based reliability systems. Comparing the complexity of FRS1 and FRS2, the FRS2 is more complex than FRS1. However, it considers also the security; therefore, it can be used in real application for secure systems.Peer ReviewedPostprint (author's final draft
