Unmanned Air Vehicles (UAV) have been used to perform different type of missions. Many of these civilian and military missions require information exchange between UAVs, which is performed by using routing protocols for wireless ad hoc networks. An efficient routing protocol for unmanned flying ad hoc networks (UFANETs) plays a critical role for data transmission during various applications. In the literature, there are many studies for mobile ad hoc networks (MANET) routing protocols. Due to high mobility and frequent topology changes, most of these studies are not applicable to flying ad hoc networks. Although there are some studies for UFANETs, none of them use cross layer metrics for routing decision and maintenance. In this thesis, a new routing lifetime decision method is proposed for UFANETs by using cross layer metrics. The proposed method uses signal to noise ratio (SNR), frequency offset due to Doppler Effect and received signal power (RSSI or RSRP) parameters as cross layer metrics. This novel approach is applied to Ad Hoc On Demand Distance Vector (AODV) routing protocol and controls the remaining routing life time of the active routes. Simulations of the new approach and basic AODV protocol are done by using INET Framework of OMNET++ simulation tool. Results show that the proposed method improves the routing lifetime decision performance in terms of end-to-end latency, total number of routing overhead messages and successful data transmission ratio.

Modeling and simulation of a small-sized Tiltrotor UAV
Çakıcı, Ferit; Leblebicioğlu, Mehmet Kemal (2012-10-01)
Unmanned aerial vehicles (UAVs) are remotely piloted or self-piloted aircrafts that can carry cameras, sensors, communication equipment and other payloads. Tiltrotor UAVs provide a unique platform that fulfills the needs for ever-changing mission requirements, by combining the desired features of hovering like a helicopter and reaching high forward speeds like an airplane, which might be a force multiplier in the battlefield. In this paper, the conceptual design and aerodynamical model of a realizable small...
Solving the area coverage problem with UAVs: A vehicle routing with time windows variation
Semiz, Fatih; Polat, Faruk (Elsevier BV, 2020-4)
In real life, providing security for a set of large areas by covering the area with Unmanned Aerial Vehicles (UAVs) is a difficult problem that consist of multiple objectives. These difficulties are even greater if the area coverage must continue throughout a specific time window. We address this by considering a Vehicle Routing Problem with Time Windows (VRPTW) variation in which capacity of agents is one and each customer (target area) must be supplied with more than one vehicles simultaneously without v...
Design and evaluation of a helicopter main rotor electrohydraulic control system
Düzağaç, Hasan Ali; Çalışkan, Hakan; Balkan, Raif Tuna; Department of Mechanical Engineering (2022-8-26)
Helicopters are widely used aircrafts for several purposes. Main Rotor of a Helicopter creates necessary flight forces for performing flight operation. Orientation of a Helicopter Rotor System is determined and controlled manually by pilot and automatically by automatic control system via hydraulically operated flight control actuators. In this research, a novel electrohydraulically operated helicopter main rotor control system is mathematically designed and developed to improve overall performance of contr...
Numerical investigation of flow control strategies on delta wings
Yıldırım, Alper; Sert, Cüneyt; Department of Mechanical Engineering (2019)
The use of Unmanned Aerial Vehicles (UAV), Unmanned Combat Aerial Vehicles (UCAV) and Micro Aerial Vehicles (MAV) have been increasing in recent years. The researchers aim to understand the complex flow structure around low sweep angle delta wings, which are frequently used in such vehicles.They are also interested in controlling the flight performance of these vehicles by various active and passive means. This study involves numerical simulations of flows around a delta wing with a sweep angle of 45oat hig...
An Interactive Algorithm for Multi-objective Route Planning
Tezcaner, Diclehan; Köksalan, Mustafa Murat (Springer Science and Business Media LLC, 2011-08-01)
We address the route selection problem for Unmanned Air Vehicles (UAV) under multiple objectives. We consider a general case for this problem, where the UAV has to visit several targets and return to the base. We model this problem as a combination of two combinatorial problems. First, the path to be followed between each pair of targets should be determined. We model this as a multi-objective shortest path problem. Additionally, we need to determine the order of the targets to be visited. We model this as ...
