Abstract
In recent years, flying Ad-hoc networks (FANETs), which consist of small unmanned aerial vehicles (UAVs), is being used in the increasing of civilian and military applications. Due to the high mobility of the UAVs nodes, the link between the UAVs may frequently be disrupted. Hence, the existing routing protocols are inability to perform in FANETs. Motivated by this, we propose a new routing protocol named UAV-OLSR for FANETs in this paper. This protocol is based on the well-known protocol called optimized link state routing protocol (OLSR). We focus in our protocol on the lifetime of a communication link between the UAVs nodes and named link live time (LLT). We propose a new multipoint relay (MPR) selection algorithm where the UAVs node with maximum LLT is selected as the MPR. Our emulation results show that UAV-OLSR protocol outperforms OLSR in the packet loss rate, total time delay, the average time delay, and traffic received.
