Drones (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. In this study, we survey the work done towords all of practical applications of UAVs as mobile collectors for wireless sensor networks. We first studied the investigation of the proposed UAV and compared their weaknesses with each other. We also explored the technical challenges of the applications of UAVs in the wireless sensor network. ER -
