Multihop Routing of Telemetry Data in Drone Swarms
نویسندگان
چکیده
In 2015, a group of Naval Postgraduate School (NPS) professors and students set the record for largest fixed-wing unmanned aerial vehicle (UAV) swarm flown at one time. The swarm had 50 vehicles flying simultaneously and successfully demonstrated distributed decision-making with all processing occurring on swarm vehicles rather than a centralized control station. Much of the decision-making is based on telemetry data that is continuously streamed from all the nodes. At that time all telemetry data was broadcast in a single-hop radio environment using 802.11n in infrastructure mode. In the future, drone swarm distribution and mobility patterns will necessitate multi-hop communications for this telemetry data. This paper models the network currently used by the NPS drone swarm as well as potential future topologies and evaluates candidate multihop routing protocols for this application.

A Cross-Layered Protocol Architecture for Highly-Dynamic Multihop Airborne Telemetry Networks
Highly-dynamic mobile wireless communication presents unique challenges to the network at all layers, and requires the design of new protocols and mechanisms. We discuss a cross-layer aware internetwork architecture and the various mechanisms to enable reliable communication in high-velocity multihop scenarios. We introduce AeroNP, an IP-compatible network protocol that is designed for telemetr...
متن کاملDTN Gateway Architecture for Partially Disconnected Telemetry Environments
Telemetry networks often operate in challenged wireless environments, resulting in periods of disconnection. Our delay tolerant networking (DTN) gateway dynamically detects disruptions in connectivity and buffers telemetry data until connectivity is reestablished. When the connection is resumed, all buffered data is transmitted automatically in order to backfill any gaps in the telemetry stream...
متن کاملAeroRP: A Geolocation Assisted Aeronautical Routing Protocol for Highly Dynamic Telemetry Environments
With the increasing importance of networked systems for telemetry, there is a need for efficient routing algorithms in aeronautical environments. Unlike traditional mobile networks, the highly dynamic nature of airborne networks results in extremely short-lived paths, especially for multi-hop scenarios thereby necessitating domain-specific protocols. In this paper, we present the detailed desig...
متن کاملSurvey on Opportunistic Routing in Multihop Wireless Networks
Opportunistic routing is based on the use of broadcast transmissions to expand the potential forwarders that can assist in the retransmission of the data packets. The receptors need to be coordinated in order to avoid duplicated transmissions. This is usually achieved by ordering the forwarding nodes according to some criteria. The proposed opportunistic routing protocols differ in the criterio...
متن کاملAeronautical Gateways: Supporting TCP/IP-based Devices and Application over Modern Telemetry Networks
Modern telemetry networks require the use of efficient domain-specific protocols at the transport, network, and routing layers. However, the existing end-devices and services are based on legacy protocols such as TCP/IP. This necessitates translation between the legacy and aeronautical protocol. In this paper we propose an efficient translation mechanism with the help of gateways at the telemet...
