Design of a Cluster-Based Routing for Integrated Cellular and Ad Hoc Networks

This paper proposes a new heterogeneous routing algorithm that utilizes cellular network to perform routing for ad-hoc networks. When the ad-hoc network is in the coverage of a cellular network, our method takes advantage of both cellular and ad-hoc networks to collaborate in routing by using the clustering approach. If centralized management system of cellular network has information about the location of ad-hoc nodes, the routing algorithms of fixed networks can be used to find routes according to QoS demands. We utilized dual interface nodes to cooperate in routing and exchange routing information as cluster heads.
