However, in order to support collaborative learning practices, Virtual Learning Environments (VLE) are facing challenges of optimizing large-scale resources management, according to the huge growth of services, users and educational resources. Indeed, with daily rising trend on requirement's dynamic changes in service, existing VLE fall short to respond on demand. Thus, in this paper, by taking advantage of cloud computing services, we propose to design a flexible cloud-based Virtual Collaborative Learning Environment (cloud-based VCLE). The aim of this work is to exploit cloud computing potentials to facilitate collaborative knowledge construction and maximize resource sharing in VLE. The proposed platform fulfills the basic requirement of VLE to support collaborative learning, but also responds to learner's dynamic need on demand. The platform facilitates and supports students to fulfill task-driven learning in a more flexibly and friendly collaborative manner.","PeriodicalId":328833,"journal":{"name":"2016 Third International Conference on Systems of Collaboration (SysCo)","volume":"176 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116607075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With an integrated communication infrastructure, Smart Grid manages the operation of all connected components to provide reliable and sustainable electricity supplies. However, utilities from all over the world are now facing the key challenge of finding the most appropriate architecture that can satisfy their future communication needs. The architecture models given by the international organizations of standardization are conceptual, so it is insufficient to grab the relation between the network components. In this paper, we introduce the current architectures proposed by international organizations, that is, NIST, ITU and IEEE. And we highlight their limits which prevent us from understanding the communication flow in the system. Then, we present a communication infrastructure model based on these international roadmaps and guides. Unlike other architectures, this one fulfills the six functionalities that Smart Grid network must achieve. Finally, we present the communication technologies that can be used for interconnecting the components and standards for each section. This paper is a preliminary step in our work. In fact, we aim in the future work to check our architecture by modeling the system and take the step of verification and validation.","PeriodicalId":328833,"journal":{"name":"2016 Third International Conference on Systems of Collaboration (SysCo)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134305570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, the indexing and search problems have become crucial. To overcome this problem, it was proposed to use information coming from the norms and standards of educational metadata. However, this solution does not solve completely the problem. Previously, traditional information retrieval systems rely on indexing by keywords for representing pedagogical resources and queries content. This process, based on lexical matching, allows selecting pedagogical resources based on keywords shared with the query, which can reduce the accuracy of search results if the meaning of common words in the query and in the pedagogical resources is different. To overcome this issue and provide a more sophisticated search, adding semantics becomes necessary. Semantic Indexing offers a representation by the meaning of words in order to find pedagogical resources semantically relevant to the user request. We present in this paper the choice of the indexing approach used for the complementary educational resources. The main objective is to integrate this approach in the warehouse model that aims on one hand to store the complementary pedagogical resources, and on the other hand to help the user fill in the description fields of these resources.","PeriodicalId":328833,"journal":{"name":"2016 Third International Conference on Systems of Collaboration (SysCo)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122731377","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The speed up and massive uses of this network's type in a multitude domain, from large industrial applications to small every day's uses, raises new serious problematic related to security. Indeed, recent reports on cyber security highlighted the Internet of things' vulnerability, and the risks continue to increase exponentially, especially with the deployment of intelligent networks [1]. These objects connected to the Internet network will create a lot of new attack attempts and present a considerable danger for the integrity of data. To avoid disastrous consequences, security approaches must take place to ensure a set of criteria, namely: resistance to attack, data authenticity, access control and user privacy [2]. Due to limited IoT capacities as a CPU, memory, bandwidth and the energy, a new kind of protocols and concepts have been developed and/or improved to satisfy the specific quality of service of this network's type. Among these protocols we find “Message Queue Telemetry Transport” (MQTT). It is an open source protocol created by IBM that uses the Publish/Subscribe pattern and requires only a small bandwidth. In this work, we propose a new approach of secured communication based on the MQTT protocol. Indeed, in an unsecured network, we use standard techniques and algorithms of cryptography such as digital signatures, hash functions and the RSA algorithm to secure communications, data and keys exchanges in an IoT network.","PeriodicalId":328833,"journal":{"name":"2016 Third International Conference on Systems of Collaboration (SysCo)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125205059","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nowadays, MOOCs (Massive Open Online Courses) correspond to the most developed method of learning. It is a new phenomenon in e-learning which gives learners from around the world free, web-based, open access to content produced by a MOOC team. The phenomenon of MOOCs has increased remarkably by adopting collaborative mechanisms and offering new features promoting communication and exchange between learners. In this area, a big attention is given by researchers, developers and educators to the collaborative learning through Learning Management Systems (LMS), especially through learning environments and social networking. In this paper, we model the collaborative learning process in the context of a MOOC. More precisely, we focus on the evaluation process in the context of MOOCs. The proposed process is modeled with the BPMN notation and implemented via the Bonita's BPMS for future management of this process. This modeling has allowed better understanding of the considered processes and detection of different problems that can occur during an online collaborative and massive learning.","PeriodicalId":328833,"journal":{"name":"2016 Third International Conference on Systems of Collaboration (SysCo)","volume":"329 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125436050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
