An approach for the Development of adaptable Services-oriented Systems

Software engineering is marked by the emergency of two paradigms: SOC (Service Oriented Computing) and CAC (Context-Aware Computing). While SOC paradigm aims to deal in the problem of interoperability, the CAC paradigm main’s target is to challenge the adaptability of IS contexts. The adoption of these two paradigms raised the challenge of the development process of Services Oriented Systems (SOS) adaptable to the context. The purpose of this paper is to propose a model driven the development process of Services-Oriented Systems adaptable to users’ context

Energy Harvesting in wireless communication: A survey

Wireless Sensor Network is an emerging technology that has the potential to be used in futuristic applications. Sensor nodes are energy-constrained. They rely on batteries with limited capacity which impact their lifetime or mobility. To address this problem, energy harvesting technology is a solution that aims to avoid the premature energy depletion of nodes. It recharges their batteries using an energy harvesting system from the environment. In this review work, we present the concept of energy harvesting technology (EH) and Energy-Harvesting for Wireless Sensor Network (EH-WSN). We then discuss many schemes in the literature to save energy consumption of the energy harvesting sensor networks. We study their protocol design strategies and working principals. We also summarize their merits, demerits along with some future research directions
