A Review on Security Techniques in MANET

Abstract— The Mobile ad hoc network (MANET)is more prone to various attacks due to its network characteristics such as unreliable of links, lack of centralized administration and mobile nodes in the network. The defense in the network has to be increased tremendously to face the bad attacks. In order to achieve security in MANET, availability, integrity, nonrepudiation and authentication must be satisfied by the network. Providing authentication is the key issue in MANET during detection of correct route in infrastructure less network.
