In the last ten years, supported by the advances in technologies for unmanned aerial vehicles (UAVs), UAVs have developed rapidly and are utilized for a wide range of applications. To operate UAVs safely, by exchanging control packets continuously, operators should be able to monitor UAVs in real-time and deal with any problems immediately. However, due to any networking problems or unstable wireless communications, control packets can be lost or transmissions can be delayed, which causes the unstable drone control. To overcome this limitation, in this paper, we propose MuTran for enabling reliable UAV control. MuTran considers the packet type and duplicates only control packets, not data packets. After that, MuTran transmits the original and duplicate packets through multiple protocols and paths to improve the reliability of control packet transmissions. We designed MuTran and conducted a lot of theoretical analyses to demonstrate the validity of MuTran and analyze it from various aspects. We implemented MuTran on real devices and evaluated MuTran using the devices. We conducted experiments to verify the limitations of the existing systems and demonstrate that control packets can be transmitted more stably by using MuTran. Through the analysis and experimental results, we confirmed that MuTran reduces the control packet transfer delay, which improves the reliability and stability of controlling UAVs.

通过使用多个协议和路径来传输重复的控制数据包使可靠的无人机控制失效

在过去的十年中，在无人飞行器（UAV）技术的进步的支持下，UAV迅速发展并被广泛应用。为了安全地操作无人机，通过连续交换控制包，操作员应该能够实时监视无人机并立即处理任何问题。但是，由于任何网络问题或不稳定的无线通信，控制数据包可能会丢失或传输可能会延迟，这会导致无人机控制不稳定。为了克服这个限制，在本文中，我们提出了MuTran用于实现可靠的无人机控制。MuTran考虑数据包类型，仅复制控制数据包，而不复制数据数据包。之后，MuTran通过多种协议和路径传输原始数据包和重复数据包，以提高控制数据包传输的可靠性。我们设计了MuTran并进行了许多理论分析，以证明MuTran的有效性并从各个方面进行了分析。我们在真实设备上实现了MuTran，并使用这些设备对MuTran进行了评估。我们进行了实验，以验证现有系统的局限性，并证明使用MuTran可以更稳定地传输控制数据包。通过分析和实验结果，我们证实了MuTran 减少了控制数据包的传输延迟，从而提高了控制无人机的可靠性和稳定性。
