Mobile-to-Grid Middleware: Bridging the Gap Between Mobile and Grid Environments

Abstract

Abstract. Currently, access to Grid services is limited to resourceful devices such as desktop PCs but most mobile devices (with wireless network connections) cannot access the Grid network directly because of their resource limitations. Yet, extending the potential of the Grid to a wider audience promises increase in flexible usage and productivity. In this paper we present a middleware architecture 1 that addresses the issues of job delegation to a Grid service, support for offline processing, secure communication, interaction with heterogeneous mobile devices and presentation of results formatted in accordance with the device specification. This is achieved by outsourcing the resource intensive tasks from the mobile device to the middleware. We also demonstrate through formal modeling using Petri nets that the addition of such a middleware causes minimum overhead and the benefits obtained outweigh this overhead.

Dynamic Policy Management in Mobile Grid Environments

“…Later, it sends this information along with the related policies (Users policies) to the Grid Policy Server which forward it to the Single Institute Policy Server to make the final Policy decisions, then it sends the results back again to Grid Policy Server. The Grid Policy Server sends the results to the resource broker to enforce the policy results in its decisions [16].…”

Towards a UML Extension of Reusable Secure Use Cases for Mobile Grid Systems

“…On the other hand, the current grid architecture and algorithms do not take into account the mobile computing environment since mobile devices have not been seriously considered as valid computing resources or interfaces in grid communities. It has been just recently given attention to integrate these two emerging techniques of mobile and grid computing, for example, in [6], [8], [18], [24], [32], although they do not elaborate on how the mobile devices may be incorporated in the current grid architecture. All these proposals attempt to incorporate mobile devices to an existing Grid infrastructure through of tools and platforms that allow it.…”

“…Mobile Grid, in relevance to both Grid and Mobile Computing, is a Grid with the additional feature of supporting mobile users and resources in a seamless, transparent, secure and efficient way [13], [18], [25]. Grids and mobile Grids can be the ideal solution for many large scale applications being of dynamic nature and requiring transparency for users.…”

Analysis of Secure Mobile Grid Systems: A systematic approach

“…The Mobile Grid, which is relevant to both the Grid and Mobile Computing, is a full inheritor of the Grid with the additional feature that it supports mobile users and resources in a seamless, transparent, secure and efficient manner [24,32,41]. Grids and mobile Grids may be the ideal solution for many large scale applications since they are of a dynamic nature and necessitate transparency for users.…”
