Test-bed Design for Software-defined UAV Networks

Abstract

Unmanned Aerial Vehicles (UAVs) can be used to solve a wide range of problems due to their high agility and flexible configuration capabilities. However, developing and implementing these solutions become a challenging obstacle as multiple communication technologies and computing units must be coordinated to work together seamlessly. Additionally, flight control must be provided appropriately for the task at hand. In this study, we introduce our flexible UAV-based test environment and explain the setup steps. Our test environment has Wi-Fi, LoRa, and Software-defined Radio capabilities for communication. Furthermore, these communication technologies can be adjusted as needed at the network layer level using the Software-Defined Networking paradigm. Therefore, our test environment facilitates the flexible coordination of the Physical, Data Link, and Network layers. Finally, we share the test results obtained using this proposed structure in our study.

Yazılım-tanımlı İHA Ağları için Deney Ortamı Tasarımı

Abstract

İnsansız Hava Araçları (İHA) çeviklikleri ve esnek kişiselleştirilme seçenekleri ile geniş bir yelpazedeki problemlerin çözümlerinde kolay ve yaygın şekilde kullanılmaktadırlar. Fakat, bu çözümleri geliştirirken ve uygularken uygulama ortamının gerektirdiği birden fazla ve farklı telsiz haberleşme yöntemleri, benzer şekilde çeşitlilik gösteren hesaplama birimlerinin birbirleri ile uyum içerisinde işlemesi zorlu bir engel teşkil etmektedir. Bununla birlikte uçuş denetçisinin de İHA’ların görev sahasına uygun bir şekilde biçimlendirilmesi ve geliştirilmesi gerekmektedir. Bu çalışmada İHA’lar için esnek deney ortamı tanıtılmakta ve kurulum ve yürütülme basamakları anlatılmaktadır. Önerilen deney ortamı haberleşme için Wi-Fi, LoRa ve Yazılım-tanımlı Radyo erişim yöntemlerini desteklemekte ve ek olarak bu haberleşme teknolojilerini ağ katmanı seviyesinde, Yazılım-tanımlı Ağ yaklaşımı kullanılarak yatay düzlemde birleştirmekte ve karmaşık yönlendirme algoritmalarının kolayca yürütülmesine olanak sağlamaktadır. Dolayısı ile önerilen deney ortamı Fiziksel, Veri Bağlantı ve Ağ katmanlarının esnek şekilde değiştirilmesine ve bu katmanları kapsayan çözüm veya çözümlerin kolaylıkla geliştirilmesine olanak sağlamaktadır. Çalışmada son olarak bu önerilen deney ortamı kullanarak elde edilen deney detayları ve ilgili sonuçları paylaşılmaktadır.
