This paper propose mobile Grid middleware based on an adaptive QoS framework to conceal the instability and resources constraints of mobile server hosts (MSHs) are replicated and synchronized on a fixed Grid Proxy for enhanced availalabiity. However; operation time of MSHis limited by battery consumption due to the synchronization needed to maintain the freshness of replicas and the session management needed to maintain responsiveness of the MSH. According to application QoS request, the framework optimizessynchronization scheduling and polling intervals to maximize sustainability. It also adapts to dynamic resources changes including low residual battery and poor wireless connectivity by decreasing the target QoS and by reducing the aggregation period for synchronization. We built a prototype of mobile Grid Proxy on PC running Globus Toolkit.Experiments showed that the framework enables MSH to increase its operation time while meeting diverse application QoS request.
