Mobile Ad Hoc NETworks (MANETs) are comprised of highly mobile nodes that communicate with each other without relying on a pre-existing network infrastructure. Therefore they are ideally suited for use in rescue and emergency operations. These applications have increased security requirements with low acceptable delays, in order to provide high quality service. However, MANETs were not designed with security protection in mind and they are prone to several attacks. Communication in mobile ad hoc networks comprises of route discovery and data transmission phases. In an adverse environment, both these phases are vulnerable to a variety of attacks. A misbehaving node can abide well in the route discovery phase and hence be placed on utilized routes.
