Among all the wireless networks, Mobile Ad hoc NETwork (MANET) is vital and a unique application as it does not require a fixed network infrastructure. In this type of infrastructure nodes communicates directly with each other when they are in a same communication range. As MANET is having a distributed architecture and changing topology, so a traditional centralized monitoring system is no longer feasible in MANET and thus it is vulnerable to attacks. The main attacks are packet dropping or black hole attack and it is very hard to detect and prevent them.
