Semantic as an Interoperability Enabler in Internet of Things

An Inexpensive Unmanned Aerial Vehicle-Based Tool for Mobile Network Output Analysis and Visualization

“…In recent years, Unmanned Aerial Vehicles (UAVs, also referred to as drones or Remotely Piloted Aircrafts, depending on their work procedures) have improved their capabilities and performance, while at the same time becoming more economical and easier to use. It has been proven that UAVs can provide a high degree of usefulness in application domains like agriculture [ 1 ], nature monitoring [ 2 ], infrastructure maintenance [ 3 ] and, generally speaking, secure information transfer among remote locations and devices [ 4 ] and Internet of Things environments where data collection and inference of knowledge are of major importance [ 5 ]. Indeed, UAVs have a collection of features that make them useful for environments where obtaining information from a wide area in a fast and responsive manner is of major importance: (a) they have a high degree of mobility (and therefore, they can perform manoeuvres and travel to areas where other bigger devices or humans might not be able to go, due to distance, positioning or how hazardous the environment is [ 6 ]); (b) they tend to be inexpensive to acquire and use (and can be employed without requiring large amounts of economic resources); (c) they are portable (therefore, they can be taken from/to different places without high requirements in space or storage room); (d) they can provide large amounts of data in a comparatively small amount of time (so they come in handy for any application that involves data, even in a big-data-like fashion [ 7 ]); (e) they can be used both in a piloted and autonomous manner (so they can be left to perform tedious tasks without the constant need of supervision).…”
