Abstract - Flying Ad-Hoc Networks (FANETs) have become
very popular nowadays and have been widely used in various applications. However, due to the high mobility of Unmanned Aerial Vehicles (UAVs) and frequent topological changes, there are many challenges in FANETs such as routing path failure, packet loss, and frequent interruption of the link between UAVs. The unique characteristics of FANETs make designing routing protocols a difficult task. In this paper, we propose a routing protocol named Intelligence-OLSR (INT-OLSR) for FANETs. This protocol improves the routing performance of the Optimized Link State Routing protocol (OLSR) based on the Ant Colony Optimization algorithm (ACO) for efficient communication and obtain the most stable routes and the selfadaptation of the network in case of any topological changes. Our simulation was performed using NS2 simulator. The evaluation results show that the proposed protocol (INTOLSR) performs better than the OLSR protocol in terms of packet delivery ratio, average time delay and throughput.

2. FANET ROUTING PROTOCOLS There are several topology-based routing protocols that have been developed to suit the unique characteristics of FANET networks.
Key Words: Flying Ad-Hoc Networks (FANETs), Optimized Link State Routing protocol (OLSR), Ant Colony Optimization Algorithm (ACO),Optimal Routing, Unmanned Aerial Vehicles (UAVs).
These protocols are based on information about links between nodes which rely on IP addresses for packet exchange between connected nodes. Topology-based routing protocols in FANET can be classified into three main categories [4]:
1.INTRODUCTION Recently, Flying Ad-Hoc Networks (FANETs) have become widespread as they have been used in a wide range of applications by organizing a group of Unmanned Aerial Vehicles (UAVs) to cooperate with each other in order to accomplish many complex tasks with high efficiency [4] [1]. FANET is a distributed wireless network that allows UAVs to communicate with each other without a fixed infrastructure. It is an extension of Mobile Ad-Hoc Networks (MANETs) and Vehicle Ad-Hoc Networks (VANETs) [2].
2.1 Proactive Routing Protocols These protocols are also known as table-driven routing protocols, because they pre-select routes before they are used even when there is no data flow over those routes, and maintain routing tables for the entire network by routing private information in the network from node to node. The most widely used proactive routing protocols are as follows[5]:
Due to their versatility and flexibility, UAVs have been used in many military and civil applications, such as remote sensing operations, border control, fire management, disaster , and search operations [3]. However, there are a lot of peculiarities in the behavior of UAVs, such as unpredictable movement, high speed, irregular distribution across the network, and frequent changes in the network topology, thus, makes the design of FANET routing protocols a very complex task [4].
