Abstract: The Unmanned Aerial Vehicles Ad hoc Network (UAANET) consists of multi UAVs through multi-hop wireless communication links, and it can execute missions more efficiently compared with the single UAV. Due to its dynamic topology, fast-moving velocity, and unstable radio channel quality, message delivery in UAANET often suffers from increased delays and packet loss. In particular, the command messages and the coordination messages are lost or significantly delayed, which results in uncontrolled UAV, failure of the task execution, or even the crash of UAANET. For the reliability and performance of UAANET, the message scheduling scheme should be taken into account. In this paper, we propose a Prioritizing-based Message Scheduling algorithm (PMS) to provide reliable transmission of command messages and coordination messages. The proposed algorithm assigns different priorities to the messages based on the content of messages and dynamic context factors, and then schedules the messages respectively. Simulation results verify that PMS can substantially increase the reliability of UAANET.
