The technology of unmanned aerial vehicles (UAVs) has gone through revolutionary improvements, which have led to highly advanced UAVs that come in numerous sizes, capabilities, and functions. These days the wireless sensor networks that consist of battery-limited nodes are using the UAVs for data gathering purposes. UAV helps significantly reduce the energy consumption used in data transmission, reduce radio frequency interference that can be caused with the hidden terminal and collision problems that are present in the multi hop data routing approach. UAV assisted WSN can have better network lifetime as the sensor nodes do not have to forward the data to the sink node. This also improves the QoS parameters of the network.
