Performance Analysis of IEEE 802.11p and IEEE 802.11n based on QoS for UAV networks

Missions involving multiple Unmanned Aerial Vehicles (UAVs) typically require UAVs to share their state of execution with each other in a dynamic way to support the execution of cooperative/collaborative tasks. Providing survivability and QoS in such communication are important research challenges when searching for reliable transmission of data. Since VANETs have similar characteristics to UAV networks regarding mobility and dynamic change of topology, using the IEEE 802.11p (WAVE) for UAV networks has become more frequent. In this context, the aim of this work is to provide a performance comparison between IEEE 802.11p (WAVE) and IEEE 802.11n (WiFi) standards. A simulated scenario of UAV's mobility was developed by integrating NS-3 and SUMO simulation tools. We compare and analyze IEEE 802.11n 2.4 GHz and 5 GHz using DCF and EDCA coordination functions, and IEEE 802.11p EDCA performances. Different from other works, this work evaluates these standards in respect to reliability and survivability of the UAV network while transmitting different access classes of ToS.
