Abstract
Today, with scientific and technological advances in robotics, artificial intelligence, control and computers, land, air, and sea vehicles, they have been considered. Unmanned aerial vehicles (UAVs) have also significantly improved and are very useful for many important applications in the business, urban and military environment. One of the important uses of UAVs in Wireless Sensor Networks (WSNs) is that devices with low energy and may not be able to communicate in large areas. Nevertheless, a UAV can provide a tool for collecting the data of WSN from one device and transmitting it to another device. This article focuses on the field of research on practical applications of UAVs as mobile collectors for wireless sensor networks. First, the investigations of the proposed UAV were studied and compared their weaknesses with each other. Then, the technical challenges of the applications of UAVs in the wireless sensor network were explored.
Highlights
In the near future, millions Unmanned aerial vehicles (UAVs), known as drone, are expected to quickly operate in different parts of our everyday lives and provide massive services [1]
Drones can play a key role in Wireless Sensor Networks (WSNs), which consist of devices with a limited battery size, like health monitors and sensors [2]
Because of their energy constraints, these devices can not normally be transmitted over long distances. In this WSN cases, UAV can dynamically move towards devices of WSN, gather data of WSN and transmit it to other devices which are out of the communication ranges of the transmitters.See Figure 1
Summary
Millions UAVs, known as drone, are expected to quickly operate in different parts of our everyday lives and provide massive services [1]. Drones can play a key role in Wireless Sensor Networks (WSNs), which consist of devices with a limited battery size, like health monitors and sensors [2] Because of their energy constraints, these devices can not normally be transmitted over long distances. The main applications of communications supported by the UAV can be divided into three categories [3]: 1) Coverage everywhere with the UAV, in which UAVs are used to provide integrated telecommunication coverage in the targeted area to assist existing ground telecommunication infrastructures In this case, UAVs act as aeriel base stations (BS) [4]. Compared with the collection of terrestrial data sets, aerial data collection can be controlled using an UAV that has faster movement This can increase the search speed and visit nodes, and reduce the lifecycle of WSN data when network has a large scale sensor network. Related articles in this area can be classified according to the previous challenges, which we will examine in each of these categories
