Today’s world demands more efficient learning models that allow students to play a more active role in their education. Technology is having an impact on how instruction is delivered and how information is found and share. Until very recently, the educational models encouraged memorization as an essential learning skill. These days, technologies have changed the educational model and access to information. Knowledge is available online, mostly free, and easily accessible. Reading, sharing, listening and, doing are currently necessary skills for education. Mobile devices have become a complete set of applications, support, and help for educational organizations. By conducting an analysis of the behavior and use of mobile devices on current students, efficient educational applications can be developed. Although there are several initiatives for the use of mobile learning in education, there are also issues linked to this technology that must be addressed. In this work, we present the results of a literature review of mobile learning; the findings described are the result of the analysis of several articles obtained in three scientific repositories. This work also lists certain issues that, if properly addressed, can avoid possible complications to the implementation of this technology in education.

“…Service composition is the integration of any existing e-services communicated over the Internet through wired media [4]. Recently, the research [5][6][7][8][9][10][11] on service composition over infrastructure-less networks has evolved enormously. Most of the works in the literature deliberate that the services available on the wired network are easily accessible; whereas, the services offered by the wireless network can be accessed by matching service composition protocols with infrastructure-less protocols.…”

MANET is a mobile ad hoc network with many mobile nodes communicating without a centralized module. Infrastructure-less networks make it desirable for many researchers to publish and bind multimedia services. Each node in this infrastructure-less network acts as self-organizing and re-configurable. It allows services to deploy and attain from another node over the ad hoc network. The service composition aims to provide a user’s requirement by combining different atomic services based on non-functional QoS parameters such as reliability, availability, scalability, etc. To provide service composition in MANET is challenging because of the node mobility, link failure, and topology changes, so a traditional protocol will be sufficient to obtain real-time services from mobile nodes. In this paper, the ad hoc on-demand distance vector protocol (AODV) is used and analyzed based on MANET’s QoS (Quality of Service) metrics. The QoS metrics for MANET depends on delay, bandwidth, memory capacity, network load, and packet drop. The requester node and provider node broker acts as a composer for this MANET network. The authors propose a QoS-based Dynamic Secured Broker Selection architecture (QoSDSBS) for service composition in MANET, which uses a dynamic broker and provides a secure path selection based on QoS metrics. The proposed algorithm is simulated using Network Simulator (NS2) with 53 intermediate nodes and 35 mobile nodes of area 1000 m × 1000 m. The comparative results show that the proposed architecture outperforms, with standards, the AODV protocol and affords higher scalability and a reduced network load.

Abstract-Software Product Line (SPL) is concerned with the sharing of common features within a family of products. It offers benefits, proven in several industry success cases. Regardless of its success, such a reuse-based development methodology has not been well explored in educational fields yet, as mobile platforms. In a different but related perspective, several initiatives have been undertaken as an attempt to improve the teaching of programming; however, no reuse approaches have been considered. In this paper we discuss the most significant approaches and methodologies for the conception of an SPL architecture according to the specificities of mobile devices and the teaching of programming. As main contributions, we highlight the identification of a set of approaches that support the conduction of the initial SPL processes, the design of a conceptual architecture model, and its qualitative evaluation with stakeholders.
