Abstract
Existing Unmanned Aerial Vehicles (UAVs) mainly rely on the direct ground-to-UAV communications over the unlicensed spectrum, which can only operate within the visual line of sight. Integrating UAVs into cellular networks is a promising solution to extend the range but poses new challenges to the transport protocols. To ensure the flight safety, the transmission of UAV commands and mission-related data is required to be reliable with low latency. In this paper, we propose a Low-latency Reliable Transmission (LRT) protocol by exploiting the rateless and online properties of online network coding. We design the LRT, implement it, and evaluate its performance in terms of the in-order per message delay. Experimental results show that LRT can provide low-latency transmission service comparable to that of UDP while giving the same reliability of TCP, which makes it an attractive option for Network-Connected UAV applications.

Many use cases of UAVs require beyond visual LOS communications. Mobile networks offer wide-area, high-speed, and secure wireless connectivity, which can enhance control and safety of UAV operations and enable beyond visual LOS use cases. In this article, we share some of our experience in LTE connectivity for low-altitude small UAVs. We first identify the typical airborne connectivity requirements and characteristics, highlight the different propagation conditions for UAVs and mobiles on the gr...

Meeting the diverse delay requirements of emerging wireless applications is one of the most critical goals for the design of ultra-dense networks. Although the delay of point-to-point communications has been well investigated using classical queueing theory, the delay of multipoint- to-multipoint communications, such as in ultra-dense networks, has not been explored in depth. The main technical difficulty lies in the interacting queues problem, in which the service rate is coupled with the statu...

Current approaches to the practical implementation of network coding are batch-based, and often do not use feedback, except possibly to signal completion of a file download. In this paper, the various benefits of using feedback in a network coded system are studied. It is shown that network coding can be performed in a completely online manner, without the need for batches or generations, and that such online operation does not affect the throughput. Although these ideas are presented in a singl...

Random Linear Network Coding (RLNC) is a popular coding scheme to improve communication over lossy channels. For packet streaming applications (video streaming, general IP streams), recent research has shown that sliding window schemes can improve in-order delay properties compared to the block/-generation based coding. However, implementing sliding window RLNC with a limited coding window poses new challenges in both theoretical and engineering aspects. We introduce the first practical generati...

Application-Level Forward Erasure Correction (AL-FEC) codes are a key element of telecommunication systems. They are used to recover from packet losses during large scale content distribution, for instance within the FLUTE/ALC (file transfers) and FECFRAME (continuous real-time media transfers) protocols of the 3GPP Multimedia Broadcast and Multicast Services (MBMS) standard. However currently standardized and deployed AL-FEC codes for these protocols (e.g., Raptor(Q) or LDPC-Staircase) are all ...

Wireless communication systems that include unmanned aerial vehicles promise to provide cost-effective wireless connectivity for devices without infrastructure coverage. Compared to terrestrial communications or those based on high-altitude platforms, on-demand wireless systems with low-altitude UAVs are in general faster to deploy, more flexibly reconfigured, and likely to have better communication channels due to the presence of short-range line-of-sight links. However, the utilization of high...

This paper introduces theKodo network coding library. Kodo is an open source C++ library intended to be used in practical studies of network coding algorithms. The target users for the library are researchers working with or interested in network coding. To provide a research friendly library Kodo provides a number of algorithms and building blocks, with which new and experimental algorithms can be implemented and tested. In this paper we introduce potential users to the goals, the structure, an...

Application Layer Forward Error Correction (AL)-FEC is increasingly being employed in the emerging wireless multimedia applications, where the multimedia data is sent along with repair data that can be used at the receiver to recover any losses. Raptor codes and Random Linear Codes (RLC) have emerged as promising rateless coding solutions. The DVB-H standard has adopted Raptor codes for IP datacasting, whereas for real-time communications, Reed-Solomon (RS) codes are used as link-layer FEC. This...

This monograph describes the theory behind Raptor codes, and elucidates elements of the processes behind the design of two of the most prominent members of this class of codes: R10 and RaptorQ (RQ). R10 has already been adopted by a number of standards' bodies, and RQ is in the process of entering various standards at the time of writing of this monograph. The monograph starts with the description of some of the transmission problems, which inspired the invention of Fountain codes. Thereafter, L...
