On-Demand Anonymous Routing (ODAR)
Lichun Bao, Rex Chen, Denh Sy · WORLD SCIENTIFIC eBooks · 2009
Routing in wireless ad hoc networks are vulnerable to traffic analysis, spoofing and denial of service attacks due to open wireless medium communications. Anonymity mechanisms in ad hoc networks are critical security measures used to mitigate these problems by concealing identification information, such as those of nodes, links, traffic flows, paths and network topology information from harmful attackers. We propose ODAR, an On-Demand Anonymous Routing protocol for wireless ad hoc networks to enable complete anonymity of nodes, links and sourcerouting paths/trees using Bloom filters. We simulate ODAR using J-Sim, and compare its performance with AODV in certain ad hoc network scenarios. Privacy concerns are increasing in the Internet and wireless networks due to the mounting intrusions and attacks. Anonymity that hides the identities of various components or parts of a network communication is one of the
