Middleware in Ubiquitous Computing

IoT Efficient Design Using WComp Framework and Discrete Event Modeling and Simulation

“…The lines [2][3][4][5] in the second code block below concern the modification of the lamp status depending on the old state. If the lamp status is "light_ON", we alter the state to "light_OFF" else we keep the initial state ("light_ON").…”

“…The difficulty is to propose a compositional adaptation which aims to integrate new features that were not foreseen in the design, remove or exchange entities that are no longer available in a given context. We have being focused on the WComp environment [2,3] which is a prototyping and dynamic execution environment for Ambient Intelligence applications created by the Rainbow research team of the I3S laboratory, hosted by University of Nice-Sophia Antipolis and CNRS. It uses lightweight components to manage dynamic orchestrations of Web service for device [4], like UPnP (Universal Plug and Play), discovered in the software infrastructure.…”

Discrete Event Modeling and Simulation for IoT Efficient Design Combining WComp and DEVSimPy Framework

“…Mechanism to address this concern must be proposed by middleware for ubiquitous computing. Several variety of middleware tools have been defined in the recent years in order to perform ubiquitous computing : (a) HOMEROS (Seung et al, 2004) middleware architecture which allows high flexibility in the environment of heterogeneous devices and user ; (b) EXEHDA (Lopes et al, 2014) middleware which manages and implements the follow-me semantics in which the applications code is installed on-demand on the devices used and this installation is adaptive to context of each device ; (c) WComp (Hourdin et al, 2013) middleware based on a software infrastructure, a service composition architecture and a compositional adaptation mechanism. In this paper we are interested in the WComp middleware.…”
