Intrusion detection systems (IDS) have become one of the most important components
in the wired network security infrastructure. With the emergence of wireless Ad-hoc
networks and their implementations in our day to day life, lead to a solid security
requirement. Traditional IDS (wired one) may not be suitable for wireless ad-hoc
networks as wireless networks are infrastructureless with not center point of
monitoring and very different operative environment. For wireless networks, an IDS
should be distributed and cooperative. Keeping the above requirement in mind, we
observe that our immune system is the living example of such a robust IDS. Inspired
by the human immune system, a new branch of intelligent computing is emerging as
Artificial Immune System (AIS). In this presentation, we try to summarize few
research attempts to build AIS based IDSs for wireless ad-hoc networks.
