Abstract
This paper studies the two-hop transmission relying unmanned aerial vehicle (UAV) relays which is suitable to implement in the internet of things (IoT) systems. To enhance system performance in order to overcome the large scale fading between the base station (BS) and destination as well as achieve the higher spectrum efficiency, where non-orthogonal multiple access (NOMA) strategies were typically applied for UAV relays to implement massive connections transmission. In particular, outage probability is evaluated via signal to noise ratio (SNR) criterion so that the terminal node can obtain reasonable performance. The derivations and analysis results showed that the considered fixed power allocation scheme provides performance gap among two signals at destination.The numerical simulation confirmed the exactness of derived expressions in the UAV assisted system.

Summary
Wireless communication technology has pace to adapt demand with rapid development of new techniques. The decreasing cost of unmanned aerial vehicle (UAV) network together with the dramatical innovation of UAV-based manufacturing technology provides connections as some difficulties happen. Some applications such as weather monitoring systems, forest fire prevention technology, man-v-machine are provided by many new UAV applications appeared in the civilian market. Higher cost and difficulty in the construction of cellular stations happen and such situation leads to solutions of the IoT network by employing the UAV relays assisted Communication. UAV-based network benefits to infrastructure development by providing itss convenient implement and lower cost, high-altitude assisted transmission [4, 5]. In [16], the throughput aspects of the cognitive radio as applying NOMA techniques were discussed and compared
