Sruthi R, Vijayakumar R . Prevention of MANETS from Malicious Node Attacks. International Journal of Computer Applications. 112, 14 ( February 2015), 23-25. DOI=10.5120/19735-1529
Mobile Ad-hoc Network (MANET) is the network which forms when needed with no existing or fixed infrastructure. It is an autonomous system of mobile hosts connected by wireless links. The mobile hosts are free to move independently in any direction. Due to the infrastructure-less design and self-organized mobile nodes the MANETs are prune to different problem, such as routing attacks, security breach problem, one among them is malicious node attack. The malicious node attack is an active attack which causes severe damage to the network. The malicious node can misroute, modify data packets. The proposed trust based mechanism is used to detect and isolate the malicious node from the network. The trust mechanism evaluates the trust value along with the reputation score and isolates the malicious node from active path. The proposed model is simulated using network simulator (NS2).
