Next generation grids and wireless communication networks: towards a novel integrated approach

Abstract

One of the most promising trends for next generation networks is to consider an integrated approach to the communication infrastructure and the processing layer. In particular, the introduction of broadband and reliable wireless networks allows the interaction of a huge number of devices all creating a single network. On the other hand, the grid paradigm is considered as one of the most promising approach for pervasive and dynamic applications. Aim of this paper is to present a novel integrated approach between grid paradigm and wireless networks by highlighting the main advantages of their cooperation. In particular, it will be shown here how a wireless heterogeneous network can be exploited for implementing a pervasive and dynamic grid (mobile grid) and, on the other hand, a mobile grid allows the optimization of the communication infrastructure. The integrated approach can be an effective method for solving applications, such as emergency management, where a huge amount of data derived from a wireless infrastructure needs to be processed efficiently and adaptively, and the traffic flow in the wide area wireless networks needs to be coordinated and optimized.

Wireless Communication Protocols for Distributed Computing Environments

“…• expressing the self-adaptiveness directly in the distributed application demanding to it the self-configuration problem (Aldinucci et al, 2008;Fantacci et al, 2009;Huebscher & McCann, 2008;Vanneschi & Veraldi, 2007). In particular (Fantacci et al, 2009) describes a pervasive gird application as a set of components interconnected by logical communication channels; a component provides a pool of functionalities and can be deployed in different versions characterized, e.g., by different memory footprints, CPU usages, etc.…”

“…In particular (Fantacci et al, 2009) describes a pervasive gird application as a set of components interconnected by logical communication channels; a component provides a pool of functionalities and can be deployed in different versions characterized, e.g., by different memory footprints, CPU usages, etc. In this model the self-adaptiveness problem is addressed by switching at run-time between the versions of the same component deployed in the computing nodes.…”

Network virtualization as an integrated solution for emergency communication

“…Some issues (like the need for distributed authentication) are identified. Fantacci et al go a step further in [24] integrating the (same) communication infrastructure and the processing layer as a grid, proposing the ASSISTANT programming model.…”

“…As also proposed by different authors [40,29,30,15,24,37] and projects [3,2], a wireless mesh network deployed at crisis sites can be a great tool to allow a fast setup of basic communication infrastructure providing higher bandwidths, interconnected by other publicly available or dedicated networks like TETRA or satellite or 3G. As described in [21], VPAN allows usage and fast deployment of this mesh network as it takes care of security, mobility and interconnecting remote clusters seamlessly.…”

Architecture for Wireless Grids

“…Today, all the intelligence is in the edge nodes of the networks, which implies that information is now scattered across different devices [3,4]. Therefore, one of the most important trends for NGNs is to consider an integrated approach to the communication infrastructure and the processing layer [5].…”
