MANET is a Mobile Ad hoc NETwork in which multi-hop communication takes place. It is capable of working without any fixed infrastructure hence it is also called as infrastructure-less network. As it is infrastructure-less, nodes are free to move from one place to another. Hence, network topology changes dynamically. These characteristics of MANET make it vulnerable to variety of attacks. Intrusion Detection System (IDS) provides an effective way to detect attacks that occurs in MANET. Some of the existing IDSs in MANET fail to work in case of dynamic network topology.
