An enhanced data replication mechanism for mobile grid environment

Abstract

Grid computing is a technology which provides support for flexible and controlled sharing of resources that are required to solve computationally intensive applications As it is open highly heterogeneous and scalable it is the basis and enabling technology for pervasive and utility computing Yet it has become essential to support seamless computing and communication for mobile users which would offer flexibility and increased information availability Due to the rapid technology advancements enabled mobile devices more powerful in terms of computing and ubiquitous in terms of connectivity Besides the evolution of 3G and 4G wireless technologies enhance the spectral efficiency to support high data rates and mobile broadband everywhere Nowadays the wireless devices such as laptops are enriched with substantial amount of computing power equal to their static counterparts This paradigm shift has given rise to a new mechanism called Mobile Grid Mobile grid enables both the mobility of the users requesting access to a fixed grid and the resources that are themselves part of the grid
