Abstract
MANET has no clear line of defence so it is accessible to both legitimate network users and malicious attackers. In the presence of malicious nodes, one of the main challenges in MANET is to design the robust security solution that can protect MANET from various DDoS attacks. Different mechanisms have been proposed using various cryptographic techniques to countermeasure these attacks against MANET. These mechanisms are not suitable for MANET resource constraints, i.e., limited bandwidth and battery power because they introduce heavy traffic load to exchange and verifying keys. In this study, the current security issues in MANET are investigated. Particularly, the researchers have examined different DDoS attacks and some detection methods like profile-based detection specification-based detection as well as existing solutions to protect MANET protocols.
