Many Location-aware routing protocols have been proposed for the mobile ad hoc networks in recent years. The efficiency of the routing protocols can be improved by considering the location information of the mobile nodes. However, the mobility characteristics of the mobile node have not been taken into account in most of the related work. In this paper, the proposed Velocity Aided Routing (VAR) protocol determines its packet forwarding scheme based on the relative velocity between the intended forwarding node and the destination node. The routing performance can be further improved by the Velocity and Location Aided Routing (VLAR) protocol, which combines the Location Aided Routing (LAR) protocol with the VAR algorithm. Two types of motion predictive models, the Gauss-Markov Mobility Model and the Constant Speed Mobility Model, are incorporated in the design of the VAR and VLAR algorithms. Simulation studies show that the proposed VLAR protocol outperforms other routing algorithms, especially for confined network topologies with higher mobility.
