a new intrusion detection system to deal with black hole attacks in mobile ad hoc networks

by extending wireless networks and because of their different nature, some attacks appear in these networks which did not exist in wired networks. security is a serious challenge for actual implementation in wireless networks. due to lack of the fixed infrastructure and also because of security holes in routing protocols in mobile ad hoc networks, these networks are not protected against attacks. for example in black hole attack, an attacker catches packets and throw them away, instead of forwarding them to their destinations. by using wireless intrusion detection systems, wireless networks can be protected. in this study, we introduce a new intrusion detection system to encounter black hole attack. this system is based on a combination of anomaly based intrusion detection (abid) and specification based intrusion detection (sbid), we also use a new intrusion response. the analysis of simulation results (with ns-2) show that our method is success by using three measures: throughput, packet loss rate and packet delivery rate in comparing with abid and sbid.
