Abstract-Grid Computing is a concept, a network, a work in progress, part hype and part reality, and it is increasingly capturing the attention of the computing community. It uses clusters of personal computers, servers or other machines. They link together to tackle complex calculations. In part, grid computing lets companies harness their unused computing power, or processing cycles, to create a type of supercomputer. Wireless grids extend the capability of grid computing to wireless devices. The number of users using laptops, PDAs, cell phones, and other wireless devices is increasing leading to more networked wireless devices, and creating a vast collective potential of unexploited resources. Wireless grid computing with its model of coordinated resource sharing may provide a way to utilize such resources that are normally distributed throughout a grid. We may have Gridnet in the future as we have Internet today. This paper presents a state-of-the-art review of wireless grid computing.Index Terms-Grid computing, Wireless grid computing, Grid standards.
I. INTRODUCTION Grid computing [1], [2]is an important and developing computing initiative that involves the aggregation of network connected computers to form a large-scale, distributed system for coordinated problem solving and resource sharing. By spreading computing workload across the distributed system of computers, grid users can take advantage of enormous computational, storage, and bandwidth resources that would otherwise only be available within traditional multiprocessor supercomputers. To give an analogy, grid computing is similar to power grids, where user does not need to know anything about what stays beyond the socket. One can absorb all the power he/she wants according to the agreement with electrical society. Grid computing has attracted worldwide attention in a variety of applications ranging from physics, chemistry, environment, aerospace and healthcare systems [3], [4].Wireless grid computing is evolving because of the fast developments in wireless technology and grid computing technology. Wireless grids extend the capability of grid computing to wireless devices. Wireless grid computing supports sharing of these resources by mobile, and fixed wireless devices within the virtual organizations. It may include devices like laptops, mobiles, PDAs, sensors, etc., *was with Basaveshwar Engineering College, Bagalkot, Karnataka, India.
