Flying ad hoc networks (FANETs) belong to the family of mobile (MANETs). They have gained high popularity due their extensive applications in various industries such as emergency management, military missions, and supervision. However, these face important challenges guaranteeing reliable data transmission because dynamic nature lack infrastructure. In this paper, a new version greedy perimeter stateless routing scheme called GPSR+AODV is proposed FANET. It combines two schemes, namely GPSR AODV, member geographic methods. GPSR+AODV, each UAV consists certain hello broadcast period that adjusted based on prediction its spatial coordinates future. Additionally, modifies forwarding process restricts search space for finding next-hop node by obtaining refined candidate set, calculated cylindrical coordinate system. Then, set evaluated under fitness function, most suitable with maximum determined. This function combination four criteria, relative velocity, energy level, buffer capacity, distance destination. When failing process, changes technique uses an AODV-based select best node. Lastly, implemented NS2 simulator, simulation results show successful performance terms packet delivery rate, throughput, delay compared AGGR, AeroRP, GPSR. overhead higher than AGGR.
