More on Castor: the Scalable Secure Routing Protocol for Ad-hoc Networks
2009 (English)Report (Other academic)
Wireless ad hoc networks are inherently vulnerable,as any node can disrupt the communication of potentially anyother node in the network. Many solutions to this problem havebeen proposed. In this paper, we take a fresh and comprehen-sive approach, simultaneously addressing three aspects: security,scalability and adaptability to changing network conditions. Ourcommunication protocol, Castor, occupies a unique point in thedesign space: it does not use any control messages except simplepacket acknowledgements, and each node makes routing decisionslocally and independently of other nodes without exchangingrouting state with them. This novel design makes Castor resilientto a wide range of attacks and allows it to scale to large networksizes and to remain efficient under high mobility. We compareCastor against four representative protocols from the literature.Our protocol achieves up to two times higher packet deliveryrates, particularly in large and highly volatile networks, incursno or only limited additional overhead and it is able to survivemore severe attacks and recovers from them faster.
