In order to make communication among nodes, the nodes dynamically establish paths among one another. Here each node participates in routing by forwarding data to other nodes. Though each node in MANET will act as host as well as router. In MANET nodes can directly communicate to all other nodes within the radio communication range. If a node could not have direct communication then they can use intermediate nodes to communicate with other nodes. For this reason, Security is a primary concern to provide protected communication between nodes in ad hoc networks and chances of having the vulnerabilities are also more. In this paper we discuss various types of vulnerabilities in MANET. Different types of attacker attempts different approaches to decrease the network performance, throughput. In this paper the principle focus is on various types of attacks in MANETs. Keywords: MANET, Security, vulnerabilities, Attacks. I. INTRODUCTION Mobile Ad hoc Networks (MANET) are the wireless networks of mobile computing devices without any support of a fixed infrastructure. The mobile nodes in a MANET self organize together in some arbitrary fashion. A MANET is an autonomous collection of mobile users that communicate over relatively bandwidth constrained wireless links. Since the nodes are mobile, the network topology may change rapidly and unpredictably over time. These networks can be applied between persons or between vehicles in areas which are depleted .
