Identifying Intruders in MANET: Exploiting RREP Message of AODV Protocol

2. Related Work

The vast range of vulnerabilities exhibited by MANETS due to their inherent nature of communication restricts a single solution for all kinds of attacks. Researchers have proposed solutions that are either specific for a particular attack or specific to a category of attack.

Huang et al., (2003) work is based on anomaly detection mechanism, authors have proposed cluster based approach wherein cluster head collects information from neighboring nodes. Authors have extended their previous work which was based on learning approach considering various features. Here authors have proposed a protocol for formation of clusters, selection of cluster head and cluster recovery. Data related to features under consideration is recorded by nodes and transmitted to cluster head. Cluster head also collects data as it works in promiscuous mode, thereafter cluster head applies the IDS functions and tells the nodes about how the feature computation is to be done. Authors have done simulations using NS2 and Mobiemu simulator considering AODV protocol. Experimentation has been done for attacks like blackhole, sleep deprivation, selfishness, DOS etc. authors have shown that their proposed scheme is better than other existing schemes.
