In recent years, many location-aware routing protocols have been proposed for the mobile ad hoe networks. The routing performance is improved by exploiting the position information of the mobile nodes. However, the mobility characteristics of the mobile nodes have not been taken into consideration. In this paper, the proposed Predictive Mobility and Location-Aware Routing (PMLAR) algorithm incorporates the moving behaviors of the mobile nodes in the protocol design. The region for packet forwarding is determined by predicting the future trajectory of the destination node. The routing performance can be effectively improved by adopting the prediction mechanism of the proposed PMLAR algorithm. Simulation results show that the PMLAR algorithm outperforms other routing protocols under different network topologies.

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.
