PGS: Pervasive Grid Simulator Library

Abstract

Pervasive grids are service-oriented architecture,allowing sharing of resources through a flexible infrastructure, stable infrastructure providing computing power and secondly mobile devices allowing access to that power. They are characterized by their large scale in terms of number of resources, many users and geographical extent, heterogeneity and dynamism of their resources. The complexity of pervasive grids in regard to the study and evaluation of issues relating to the latter makes use of simulation that will allow study of more realistic scenarios and observe other performance criteria. In the absence of simulation tools for these platforms, the contribution of this paper is therefore to achieve a simulation tool capable of simulating any pervasive grid; we developed the library of simulation PGS "Pervasive Grid Simulator". This library is built on the basis of Java. PGS is composed of three main packages (PGS.pervasif, PGS.grille and PGS.GP).
