DSA - A Reliable Intrusion-Detection System for MANETs
MANET (Mobile Ad hoc NETwork) meant to be work under the Infrastructure less medium; it suffers from the limited bandwidth, dynamic topology problems etc. There is no base station or central control for the network and all nodes work autonomously. These characteristics are highly favorable for malicious user to entering into the Network. So the authors are discussing about the MANET IDs that is, DSA (Digitally Signed Acknowledgements) in which it checks the malicious or misbehaving nodes in three modes of operation i.e. ACK, S-ACK and MRA mode.
