Malicious Nodes Detection in AODV-Based Mobile Ad Hoc Networks ★
Jongoh Choi, Si-Ho Cha, GunWoo Park, JooSeok Song · 2005
This work provides a solution to detect malicious nodes normally operate during determination of a route over but modifies or drop data during data transmission or report wrong information regarding a normal node, using a report message and a report table that list reporter nodes and suspect nodes in AODV-based Mobile Ad Hoc Networks (MANETs). In the existing detection mechanisms, a malicious node that provides wrong information can be easily identified but cannot be removed from a network. To solve this problem, the proposed solution determines a suspect node as a malicious node when more than k lists of reporter nodes and suspect nodes are recorded in the report table in case where k malicious nodes are over the network. We evaluate the average loss rate and the average transmission rate of our solution along a number of parameters.
