Current maritime communications rely on satellite with limited resources, resulting in poorer performance compared to terrestrial wireless networks. This article proposes the concept of space-air-ground integrated networks using commercial passenger airplanes to enhance satellite-based maritime communications. A deep learning aided multi-objective routing algorithm is utilized to achieve improved coverage quality and performance.
Current maritime communications mainly rely on satellites having meager transmission resources, hence suffering from poorer performance than modern terrestrial wireless networks. With the growth of transcontinental air traffic, the promising concept of aeronautical ad-hoc networking relying on commercial passenger airplanes is potentially capable of enhancing satellite-based maritime communications via air-to-ground and multihop air-to-air links. In this article, we conceive space-airground integrated networks for supporting ubiquitous maritime communications, where the low earth orbit satellite constellations, passenger airplanes, terrestrial base stations, ships, serve as the space, air, ground, and sea layer, respectively. To meet heterogeneous service requirements, and accommodate the time-varying and self-organizing nature of space-air-ground integrated networks, we propose a deep learning aided multi-objective routing algorithm, which exploits the quasi-predictable network topology and operates in a distributed manner. Our simulation results -- based on real satellite, flight, and shipping data in the North Atlantic region -- show that the integrated network enhances the coverage quality by reducing the end-to-end delay and by boosting the end-to-end throughput, as well as improving the path-lifetime. The results demonstrate that our deep learning aided multi-objective routing algorithm is capable of achieving near pareto-optimal performance.
