What is Wireless Grid Wireless grid is a new type of resource-sharing network connected in an ad-hoc manner that allows mobile, nomadic, and fixed wireless devices to offer new resources and locations of use for grid computing. Classification of Wireless grid Applications Applications aggregating information from a range of input/output interfaces found in nomadic devices. Applications leveraging the locations and contexts in which the devices exist. Applications leveraging the mesh network capabilities of groups of nomadic devices.

Government and industry initiatives to stimulate the diffusion of high-performance broadband telecommunications links have given a fresh impetus to debates over the social and economic implications of the growing use of the Internet and other information and communication technologies (ICTs). This paper analyses how outcomes tied to ICT innovation are shaped by choices about whether and how to use, or not use, the technology to reconfigure access to people, services, information and technologies in ways that significantly change the communicative power of individuals, communities, organisations, nations and regions. It explains why these outcomes are not predetermined by the technology, but unfold over time through the complex interplay among many actors, in many arenas. A framework is presented to assist in addressing the issue of digital divides and other areas of research, policy and practice affected by the design and use of broadband Internet and related ICTs.

There have been previous hints that the transiting planet WASP-3 b is accompanied by a second planet in a nearby orbit, based on small deviations from strict periodicity of the observed transits. Here we present 17 precise radial velocity measurements and -2 -32 transit light curves that were acquired between 2009 and 2011. These data were used to refine the parameters of the host star and transiting planet. This has resulted in reduced uncertainties for the radii and masses of the star and planet. The radialvelocity data and the transit times show no evidence for an additional planet in the system. Therefore, we have determined the upper limit on the mass of any hypothetical second planet, as a function of its orbital period.
