Abstract
Relying on multi-hop communication techniques, aeronautical ad hoc networks (AANETs) seamlessly integrate ground base stations (BSs) and satellites into aircraft communications for enhancing the on-demand connectivity of planes in the air. The goal of the paper is to assess the performance of the classic shortest-path routing algorithm in the context of the real flight data collected in the North-Atlantic Region. Specifically, in this integrated AANET context we investigate the shortest-path routing problem with the objective of minimizing the total delay of the in-flight connection from the ground BS subject to certain minimum-rate constraints for all selected links in support of low-latency and high-speed services. Inspired by the best-first search and priority queue concepts, we model the problem formulated by a weighted digraph and find the optimal route based on the shortest-path algorithm. Our simulation results demonstrate that aircraft-aided multi-hop communications are capable of reducing the total delay of satellite communications, when relying on real historical flight data.
Highlights
With the proliferation of Internet services and applications, it is desirable to provide high-speed broadband access during flights above the clouds
The objective of integrating A2AC with DA2GC is to seamlessly convey long-distance tele-traffic from the ground base stations (BSs) to the destination aircraft by avoiding S2AC links, whilst maintaining reliable high-speed connections. Another potential benefit of aeronautical ad hoc networks (AANETs) relying on A2AC with DA2GC is that the integrated AANET becomes capable of reducing the latency as well as the spiralling communication cost of satellite providers

Summary
With the proliferation of Internet services and applications, it is desirable to provide high-speed broadband access during flights above the clouds. The objective of integrating A2AC with DA2GC is to seamlessly convey long-distance tele-traffic from the ground BS to the destination aircraft by avoiding S2AC links, whilst maintaining reliable high-speed connections Another potential benefit of AANETs relying on A2AC with DA2GC is that the integrated AANET becomes capable of reducing the latency as well as the spiralling communication cost of satellite providers. Our results reveal that the aircraft can be connected to the ground BS through AANETs between London Heathrow (LHR) Airport and New York’s John F Kennedy (JFK) Airport Both our simulations and real flight-data driven results demonstrate that the A2AC links are capable of extending the DA2GC coverage with the aid of lowdelay transmission.
