Mobile ad hoc computational grids (MAHCG) are combination of computational grids and mobile ad hoc networks. Computational grids allow mobile devices to share computing resources to solve computation oriented problems. Mobile ad hoc network used for networking and communication services for the nodes which forms grid. Mobile devices will form a network and share their resources for achieving a common goal. This addresses the problem of mobility of devices, as per the behavior of mobile nodes. Solution will be the prediction of device mobility; this will reduce the possibility of failure of an application. In this paper, we propose a resource allocation to stable mobile nodes in MAHCG.
