A Mobile Ad-hoc NETwork (MANET) is a group of wireless nodes that can be dynamically organized as a multi-hop packet radio network without using any existing infrastructure or centralized administration. MANETs are susceptible to the variety of attacks that threaten their operation and the provided services. MANET is severely affected by Denial of Service (DoS) attacks which become a problem for internet users. Intrusion Detection System (IDS) may act as defensive mechanism which monitors network activities in order to detect malicious activities performed by intruders and initiate proper response to malicious activity.
