Emerging technologies such as pervasive computing and Grid computing are blending multiple different resources and services (e.g., CPU cycles, data storage, sensors, visualization devices, and a wide variety of Internet-ready instruments) into a single vast pool of virtual resources that are easily and transparently accessed and utilised for demanding applications. The marriage of pervasive computing and Grid computing technologies is a fascinating research area, making possible for light devices, sensors, actuators, to enter the Grids in a win-win schema where each platform benefit from the collaboration. This e-book is in response to the increasing convergence between Grids and Pervasive Computing.The research papers selected for this e-book represent recent progresses in the field, including works on mobile ad-hoc grids, service and data discovery, context-aware application building and context accuracy, and communication. All of these papers not only provide novel ideas and state-of-the-art techniques in the field, but also stimulate future research in the Pervasive Grid environment.
