Security enhancement mechanism for Ad-hoc OLSR protocol

Abstract

In this paper, we propose security mechanism for Ad-hoc OLSR protocol. We consider the security vulnerabilities for OLSR and apply one-time digital signature for lightweight authentication of the routing messages. We also propose compromised node management mechanism in which normal nodes collaborate to report malfunctioning nodes and to isolate them from network. We finally analyze the security and overhead of our mechanism. © Springer-Verlag Berlin Heidelberg 2006.
