Abstract
The design of routing protocol is an important and key problem in unmanned aerial vehicle (UAV) communication networks. In low altitude environment, UAV information transmission is a complex task. It is an important scientific challenge to design a routing protocol that can provide efficient and reliable node to node packet transmission. This paper develops a more realistic simulation environment based on OPNET 14.5, and performs performance tests and comparisons on four classic routing protocols: Ad Hoc on demand distance vector (AODV), dynamic source routing (DSR), optimized link state routing (OLSR), and geographic routing protocol (GRP). The performance parameters such as network delay, traffic received, data dropped and throughput are compared and analyzed. The experimental results indicate that different routing protocols can be adapted to different UAV communication network scenarios. Therefore, the quantitative results can provide pertinent reference for choosing the best routing protocol in different scenarios.

Summary
With the rapid development of artificial intelligence, processor, communication module and other technologies, the performance of the communication equipment that can be carried on the UAV is getting better and better, the integrated chip is becoming more and more intelligent, and the performance of the UAV is increasing. Sarao et al [25] analysed the routing protocols of Ad Hoc networks by considering several performance metrics like throughput, end-to-end delay, normalized routing load, received packets at various speeds and pause times. It provides ideas for the evaluation method of routing protocols. In this paper, according to the characteristics of the UAV communication networks, four classic routing protocols, AODV, DSR, OLSR and GRP, are selected for simulation testing. The performance parameters such as network delay, traffic received, data dropped and throughput are compared and analyzed.
