This dissertation was written as a part of the MSc in Communications and Cybersecurity at the International Hellenic University. This dissertation begins with an analysis about the Mobile Ad Hoc Networks and their possible applications in everyday life. Moreover, an analysis of the TCP/ IP protocol stack used in MANETs is included, which is similar to the implementation of WLANs. Possible attacks against MANETs and Intrusion Detection System approaches that mitigate misbehavior are mentioned along with a review between three IDS approaches. This field is still in research and requires further improvements to provide secure and quality applications taking into consideration that the technology is new and yet, possible attacks may not have been discovered . We may not have included the best approach in this dissertation, but through the theoretical analysis and review of the three approaches, the required knowledge about IDS for MANETs can be attained together with knowledge on how to choose a more effective and efficient approach .
