Abstract In the last decade, popularity of UAVs, colloquially known as drones, has increased tremendously. Nowadays, drones are used in a wide range use-cases, such precision agriculture, surveillance, and photography. Many these use-cases can be made more efficient if multiple UAVs cooperatively (i.e., swarm). To achieve this, communication between is paramount. ensure communication, many works rely on existing infrastructure (e.g., 4G). However, rural areas, this does not exist. those...

Our specifically...

In recent years, we have seen a tremendous growth in the adoption of Unmanned Aerial Vehicles (UAVs). Nowadays, UAVs are used many different industries such as agriculture, inspection (bridges, pipelines, etc.), parcel delivery, etc. near future, this will lead to substantial increase aircraft our airspace, especially urban areas. Many existing collision avoidance approaches rely on heavy and/or expensive sensors, which limits its use for real due increased costs, weight and complexity....

In the last decade, popularity of UAVs has increased tremendously. Nowadays, many researchers are interested in UAV swarms. Coordinating a swarm is complicated task and problems should be addressed before wide-spread adoption. this work, we focus on take-off for large-scale swarms, with an extra assignment phase. The phase first stage whereby decide which ground goes to place air. A good algorithm, quick, at same time reduce total distance travelled as much possible. We assess performance...

As we experience an unprecedented growth in the field of Unmanned Aerial Vehicles (UAVs), more and applications keep arising due to combination low cost flexibility provided by these flying devices, especially those multirrotor type. Within this field, solutions where several UAVs team-up create a swarm are gaining momentum as they enable perform sophisticated tasks, or accelerate task execution compared single-UAV alternative. However, advanced based on UAV swarms still lack significant...

The field of Unmanned Aerial Vehicles (UAVs) has progressed greatly in the last years. UAVs are now used for many applications and often flown automatically. One commonly implemented feature an automatic flight is that following a mission at stable altitude. However, this altitude almost always referenced from take-off location does not take terrain profile levels into account. This critical dangerous issue because if level changes abruptly (e.g., mountain regions or buildings city), can...

In recent years, the adoption of unmanned aerial vehicles (UAVs) has widely spread to different sectors worldwide. Technological advances in this field have made it possible coordinate flight these aircraft so as conform a swarm. A UAV swarm is defined group UAVs working collaboratively carry out more complex missions or perform tasks efficiently. Common applications swarms include rescue missions, precision agriculture, and border control, among others. However, there are still certain...

As the adoption of UAVs grows steadily, more and applications are being devised. In scope urban environments, initiatives like U-Space in Europe seek to standardize regulate different operations that can be undertaken by these aircraft. order facilitate new applications, UAV research general, it is important we have a correct understanding communication with and/or between UAVs. However, find studies towards models lacking, especially regarding where obstacles (e.g. tall buildings) prone...

Since some years, research on the use of unmanned aerial vehicles (UAVs) has been very popular, and because that a wide range commercial military applications already exists. Nowadays, trend towards autonomous flying is growing steadily. Autonomous requires UAVs to have ability navigate in urban or other challenging environments without causing collisions endangering humans. To achieve this objective, safe reliable collision avoidance system (CAS) needs be used. In particular, CAS...

The use of UAVs has been growing steadily over the last years. Now that even industry is adopting them for a wide range activities, it can be said with certainty will become an important asset many enterprises. We foresee that, due to affordable prices, applications groups UAVs, also called swarms, mainstream. Swarms perform tasks faster and/or more redundancy, and other are only possible by collaborative work UAVs. However, there still challenges solved before swarms used safely. One...
