Detection of Malicious Attacks in Mobile Ad Hoc Networks (MANET)

Abstract

The highest security issue that is faced in current scenario in MANET is
infrastructure centralization. The task routing and forwarding is achieved to the max only
when the there is excellent cooperation among the participating nodes. By selfish act of few
nodes, the process of forwarding is interrupted for reasons like saving the battery power.
Malicious activities like Denial of Service (DoS) raise a security threat to MANET. Research
and analysis of various security attacks is the focal point of this project. In this system DSR
Protocol is extended with a feature of “node friendship“, which creates smooth cooperation
in an adhoc environment. Based on the above work the concept of grey hole attack can be
detected and eliminated.
