Abstract
Recently, unmanned aerial vehicles (UAVs) have been applied to various applications. In order to perform repetitive and accurate tasks with a UAV, it is more efficient for the operator to perform the tasks through an integrated management program rather than controlling the UAVs one by one through a controller. In this environment, control packets must be reliably delivered to the UAV to perform missions stably. However, wireless communication is at risk of packet loss or packet delay. Typical network communications can respond to situations in which packets are lost by retransmitting lost packets. However, in the case of UAV control, delay due to retransmission is fatal, so control packet loss and delay should not occur. As UAVs move quickly, there is a high risk of accidents if control packets are lost or delayed. In order to stably control a UAV by transmitting control messages, we propose a control packet transmission scheme, ConClone. ConClone replicates control packets and then transmits them over multiple network connections to increase the probability of successful control packet transmission. We implemented ConClone using real equipment, and we verified its performance through experiments and theoretical analysis.

In Section 4.2.2, we analyzed the lifetime of Multipath Transmission Control Protocol (MPTCP) connection with multiple interfaces, and we proposed how to determine the number of interfaces needed to meet a required reliability
To run ConClone on a portable computing board that can be mounted on unmanned aerial vehicles (UAVs), we implemented ConClone on Ubuntu 16.04 LTS, an operating system that can be used on a portable computing board [44]
Summary
Unmanned aerial vehicles (UAVs) have been used for various studies and services. Service providers are looking for ways to apply UAVs with high moving speed and three dimensional movement to various tasks [1,2,3]. As the UAV moves with very high speed, delayed transmission of control packets can lead to fatal accidents. Since it is important that control messages arrive within the time limit, the environment for transmitting control messages should be in the domain of a Time Sensitive Network (TSN). Based on these observations, we propose ConClone, a scheme for control packet transmission in order to reliably transmit control packets to the UAV over TSN
