Abstract

Ad hoc networks of mobile nodes can be used to extend or improve connectivity, and cooperative data distribution represents the basis of this approach. Cooperation in such networks can be improved by providing nodes with information on network dynamics and topology changes. This paper proposes a proactive approach to handling mobility-induced network topology changes. The approach uses signal strength trends to predict the future locations and connectivity between the network nodes. Our research is aimed towards the creation of an alternative topology in each node, where a node would keep other nodes suitability for cooperation in the data distribution. In this paper we present the initial algorithm and test the prediction method using a simulation. The algorithm is then applied in an experimental testbed where its performance was tested using real moving nodes executing a real data distribution process. The performance results show a significant improvement in terms of file transfer delay.
