Nafaâ Jabeur, Ahmed Nait Sidi Moh, Ansar Ul-Haque Yasar, Mohamed Mahdi Barkia

Personal and Ubiquitous Computing > 2017 > 21 > 6 > 1079-1096

In this paper, we address the recurring problem of node redundancy in Wireless Sensor Networks (WSNs). In addition to categorizing redundancy into different types, comprehensively formulating and representing redundancy as a dynamic matter as well as estimating it with a new analytical method, we propose an approach where sensors are competing for the identification and relocation of redundant sensors...

Lecture Notes in Computer Science > Computational Science and Its Applications – ICCSA 2005 > Tracks > 792-801

This article discusses the modelling and the evaluation of process of electronic signature (ES). According to a certain point of view, this process can be shown as a class of Dynamic Discrete Event Systems (DDES). It is in this framework that we study this class with using Petri Nets (PN) and the theory of linear systems in (max, +) algebra. We introduce these two formalisms with the aim to describe...

2015 3rd International Renewable and Sustainable Energy Conference (IRSEC)

Recently, electric vehicles (EVs) are qualified to be one of the indispensable solutions for green transport and environmental challenges. As the number of EVs sold steadily increases in the automobile market, charging infrastructures should be further developed and sophisticated. Reducing charging times of EVs is one of the major challenges for public charging stations. This challenge can be met...

2015 Third World Conference on Complex Systems (WCCS) > 1 - 7

2015 Third World Conference on Complex Systems (WCCS)

Guard Stage Milestone (GSM) approach proved its ability to specify business entities lifecycle and the associated data. Although this framework is a promising approach for business process operations modeling, the concept of physical flows is missing. In workflow modeling, we usually have three main views, the strategic, the tactical, and the operational views. These views show different aspect of...

Currently, each geographical area benefits from a set of wide range of local services, usually provided by several local entities, such as snow clearance, road works, public transportation, waste collection, fire fighting, emergency rescue authorities, etc. Despite each service fulfilling its own assigned task, they often suffer from a lack of communication and cooperation among them. Indeed, each...
