ABSTRACT
This paper reviews various security challenges and prevention methods available currently in flying adhoc networks (FANETs) that are used in different applications such as disaster rescue, battlefield communication, and device-to-device communication. Security is the major concern in FANETs, which are part of infrastructure-less wireless networks. The data collected on the unmanned aerial vehicles (UAV) side and the ground control station can be vulnerable and the node can be a malicious node on the ground as well as on the fly. Private messages between the sender of the UAV aerial base station and the receiver/ground station can be compromised. Data routing between UAVs can be vulnerable and developing a secured routing algorithm is a challenging task. UAV collaboration is also very challenging due to their dynamic path. The quality of service needs to be improved for high-quality audio, video, and images. UAV node placement is also a concern. Potential active and passive attacks include black hole attacks and grey hole attacks. Various prevention methods such as elliptic curve cryptography, physical unclonable function (PUF)-based authentication, and naive Bayes algorithm are defined in this survey paper.
