Abstract — Mobile Adhoc Networks (MANETs) is a collection of mobile nodes. Due to globalization and revolution in communication technology, growth in the deployment of wireless and mobile communication networks have been noticed. Several challenges and issues are raised by researchers working in the field of Dynamic topology and infrastructure less MANETs. Such facility generates easy installation of Ad hoc networks and provides node stability without loss of connection. In such facility packet dropping is a serious challenge for quality performance of MANETs. Exhaustive literature survey reveals that MANETs generally suffer from security attacks such as black hole attack, wormhole attack and malicious attack due to the packet dropping problems. For the minimization attack and packet dropping researchers have provided the solutions like authentication, reputation based scheme, certification based scheme, passiv
