A Mobile Ad-Hoc network, or MANET, is an infrastructure less, self-configuring network. All wireless devices in MANETs are connected through wireless links. Mobile wireless networks are more vulnerable to information and physical security threats than fixed wireless networks. Due to the use of open and shared broadcast wireless channel and due to insufficient physical protection, these networks are prone to security threats. These threats can endanger the overall functionality of mobile ad-hoc network. Various security threats show their impact at different layers. In this paper, the authors have discussed some basic routing protocols. Different security attacks have also been discussed.
