Raj Mohan Mumgai, Sandip Vijay . Malicious Node Attack Preventer (MNAP) Approach for Mobile Ad-hoc Networks (MANET’s). International Journal of Computer Applications. 58, 4 ( November 2012), 1-5. DOI=10.5120/9267-3447
A Mobile Ad-hoc network is a heterogeneous network. They have very particular features such as high mobility, multi-hop routing, open system and the absence of any fix infrastructure. An ad-hoc network faces different type of security attack. In this paper, we discuss our implementation of the AODV protocol extension namely Malicious Node Attack Preventer (MNAP). AODV extension mechanism improves the AODV behavior. MNAP used the reserved field of RREQ and RREP packet format. MNAP implements security in AODV against black-hole and gray-hole attacks. Analyzes has been done based on PDR, throughput and delay of the node selected by doing simulation on Qualnet network simulator.
