Trust-Based Flying Ad Hoc Network: A Survey

An efficient data transmission can be established by flying ad hoc networks (FANETs) that emphasized the cooperation and coordination among various unmanned aerial vehicles (UAVs) as a crucial aspect. The FANET's security becomes a crucial area for exploration due to its limited resources. Earlier research on trust-based computation in ad-hoc environments has demonstrated that previous strategies are efficient at safeguarding ad-hoc environments against a wide range of attacks. So, to curb such circumstances, trust-based management systems can be considered the major need of the hour for calculating the reputation score within the network. Trust management systems are aimed at detecting untrustworthy network nodes and keeping track of all the activities being performed by the nodes, for trust score computation. This will aid in segregating the malicious node from the network. In this article, several types of trust mechanisms of FANET have been addressed thoroughly, and several types of trust mechanism calculations are clarified primarily with the major challenges that FANET is encountering in the context of its trust management design, open research problems and solutions are being incorporated with the existing FANET-based protocols.
