In mobile ad hoc networks, the locations and resource-richness of mobile nodes vary dynamically. The information used for routing by traditional routing protocols becomes obsolete due to node mobility. To overcome this problem, a predictive location-based QoS routing scheme is needed. We present a location-delay prediction scheme, based on a location-resource update protocol, which assists a QoS routing protocol. Simulation results show that our approach can predict the location at a given instant in the future with a high degree of accuracy.
