Mobile computing technologies and wireless networks have evolved very quickly. Nowadays, many of the portable devices have significant processing power, storage and communication capacity. At the same time, grid computing technology became an important tool for collaborative work among users and organizations enabling the sharing of computing resources and services through multiple administrative domains. Due to the popularity of mobile computing, users of handheld devices form an important and new segment of the computing grid, assuming both the role of consumers and providers of resources and services. The integration of these two categories of distributed systems aims to extend the capabilities of portable devices, enabling access to a infrastructure of shared resources, as well as provide faster and easier means for grid services users to access information produced by these systems at any time and place. This work describes the MInteGrade (Mobile InteGrade), a software infrastructure that provides access to the InteGrade grid middleware from mobile devices connected through IEEE 802.11 wireless networks in infrastructure mode, and Bluetooth networks in Ad hoc mode. Through this mechanism for access to a computational grid, mobile clients can request the execution of applications on the grid, monitor the execution of applications and view the computation results already completed. The MInteGrade was designed so as to consider the dynamics of wireless networks. Specifically, it supports disconnections of devices and dynamic changes of the Ad hoc network topology, aswell as content adaptation of the output of the grid computations.
