Abstract: Flying Ad-hoc Networks (FANETs) are most popular now a days. They are used in the situations of emergency, in the case of a natural disaster, military battle fields. FANETs are the new family member of the mobile ad-hoc networks (MANETs) class. Group of Unmanned Air Vehicle (UAV) are known as Flying Ad-Hoc Networks. It completed their work without human intervention (i.e Driverless Aircraft). There are many problem arises in this kind of networks. The main problem is the communication between (UAVs). In order to solve this problem several routing protocols have been proposed for flying ad-hoc networks they are static, proactive, reactive routing protocols. This paper provides an overview of the protocols, FANET characteristics and design considerations. The main objective is to make observations about the performance of protocols.

Keywords: FANETs, Protocol, proactive, reactive, UAV.
