The huge increase in information published on the web, and its users has led to the emergence of notifications systems (Web syndication), such as the Publish/Subscribe system (Pub/sub) that helps the user to track information managed by the information collectors (RSS (Really Simple Syndication)) in real time. For pertinent use of the information issue from large data streams (Big Data) that currently...
The discovery of the requirements is a pinnacle phase in every project, and it is provided by the requirements engineering. The formalization of needs allows decision-makers to limit the interpretations of needs and it therefore facilitates the confrontation of the needs of several actors, among themselves on one hand, and with the data sources on the other. The formalization of needs offers, additionally,...
A mobile application has become an important new way to reach customers. The use of smartphones and tablets has also increased, but it's always difficult to create a new application. This requires specific knowledge and experience to successfully operate all features. The heterogeneity development tools and languages in mobile apps makes difficult to develop multi-platform mobile applications. Thus,...
Due to the large number and variety of mobile technologies and web based-components, developing the same application for these different platforms becomes a tedious task. The Model Driven Architecture (MDA) approach aims to provide an easy and efficient practical solution for developing a cross-platform application. In this work, we propose a new approach to the design of the user interface for mobile...
Recently, a great interest to routing concept in Delay Tolerant Networks has been increased notably. Deplorably, while several DTN routing protocols have been proposed, there are hardly any approaches which take as objective an attempt to improve such protocols. In this paper we focus on the predictability concept and present a new routing algorithm for DTN. We present a comparison to other existing...
Delay tolerant networks are mobile wireless networks where most of the time there is no end-to-end communication path from the source to the destination. This situation occurs if the network is sparse and partitioned into several areas due to high mobility, low density nodes or when the network extends over long distances. Traditional mobile ad hoc routing protocols are inefficient for these networks...
