WIRELESS GRIDS: APPROACHES, ARCHITECTURES, AND TECHNICAL CHALLENGES

Grid computing and grid topologies are attracting a growing amount of attention. Originating as a concept for sharing computing resources among wired participants, the grid concept is gradually been extended into the wireless world. A Wireless Grid is an augmentation of a wired grid that facilitates the exchange of information and the interaction between heterogeneous wireless devices. While similar to the wired grid in terms of its distributed nature, the requirement for standards and protocols, and the need for adequate Quality of Service; a Wireless Grid has to deal with the added complexities of the limited power of the mobile devices, the limited bandwidth, and the increased dynamic nature of the interactions involved. Depending on the nature of the interactions among the constituencies served by the wireless grid, various layouts can be envisaged. The ability of these models to address needs at the enterprise, partner, and service levels is contingent upon the efficient resolution of multiple technical challenges of the grid.
