One of the most significant challenges introduced by routing protocol in mobile networks is coping with the unpredictable motion and the unreliable behaviour of mobile nodes. In this paper, we present a hierarchical routing algorithm based on virtual mobile node VMN. A routing path can be found rapidly by exchanging path information between VMNs without accurate topology information. We discuss the routing process and the implementing details of the proposed routing algorithm. Finally, we evaluate the performance of our hierarchical routing algorithm through simulations, and the results show that the number of mobile WAVE generated by routing algorithm is well satisfied with the quality of service QoS requirements of all source and destination nodes. Furthermore, we compare the performance on VMN failure and message delivery ratio using hierarchical and non-hierarchical routing approaches, the results show that we can obtain magnitude better performance by HRA-VMN than hierarchical state routing HSR and non-hierarchical routing approach.
