“…The only standardized handover solutions are based on a non‐optimized mode. For instance, the GEO‐Mobile Radio (GMR) standard does not define any optimized mode. Vertical handover refers to the case in which the architecture combines heterogeneous technologies (DVB‐RCS(2) with LTE or with Institute of Electrical and Electronics Engineers standards as we propose in and in this paper). Handover management can rely either on specific optimized solutions or on standard generic solutions.…”

However, their integration to 4G is challenging because satellite networks have not been designed with handover in mind. The setup of satellite links takes time, and so, handovers must be anticipated long before. This paper proposes a generic scheme based on the Institute of Electrical and Electronics Engineers 802.21 standard to optimize handover and resource management in hybrid satellite-terrestrial networks. Our solution, namely optimized handover and resource management (OHRM), uses the terrestrial interface to prepare handover, which greatly speeds up the establishment of the satellite link. We propose two mechanisms to minimize the waste of bandwidth due to wrong handover predictions. First, we leverage the support of 802.21 in the terrestrial access network to shorten the path of the signaling messages towards the satellite resource manager. Second, we cancel the restoration of the satellite resources when the terrestrial link rolls back. We use OHRM to interconnect a digital video broadcasting and a wireless 4G terrestrial network. However for the simulation tool, we use a WiMAX as the terrestrial technology to illustrate the schemes. The simulation results show that OHRM minimizes the handover delay and the signaling overhead in the terrestrial and satellite networks.

“…OpenSAND is an established open-source tool for the emulation of SATCOM networks, featuring link-layer emulation 1 https://github.com/kosekmi/2022-ifip-nw-quic-proxies based on the DVB-RCS2 and DVB-S2 standards [12]. While OpenSAND shows a high degree of accuracy [13] and is widely used [13]- [16], its complex setup and parametrization is considered a major obstacle [13]. We therefore abstract the parametrization of the SATCOM emulation testbed, creating a controlled emulation environment executed on a single Linux system using different scenarios.…”

Low-Earth Orbit satellites have gained momentum to provide Internet connectivity, augmenting those in the longestablished geostationary orbits. At the same time, QUIC has been developed as the new transport protocol for the web. While QUIC traffic is fully encrypted, intermediaries such as performance enhancing proxies (PEPs) -in the past essential for Internet over satellite performance -can no longer tamper with and optimize transport connections. In this paper, we present a satellite emulation testbed and use it to compare QUIC and TCP as well as HTTP/3 and HTTP/1.1 with and without minimal PEP functionality. Evaluating goodput over time, we find that the slow start threshold is reached up to 2s faster for QUIC PEP in comparison to QUIC Non-PEP. Moreover, we find that HTTP/3 and HTTP/3-PEP outperform HTTP/1.1 and HTTP/1.1-PEP in multiple web performance scenarios, where HTTP/3-PEP improves over HTTP/3 for Page Load Time by over 7s in edge cases. Hence, our findings hint that these performance gains may warrant exploring PEPs for QUIC.

“…The framework and a prototype implementation for improving the handover performance of Mobile IP based on a variety of cross-layer and cross-domain triggers that may use QoS measurements are presented in [49]. In addition, an example of how to use media-independent handover (MIH) in an integrated satellite-terrestrial network and related signaling is described in [50].…”

An autonomous vessel uses multiple different radio technologies such as satellites, mobile networks and dedicated narrowband systems, to connect to other ships, services, and the remote operations center (ROC). In-ship communication is mainly implemented with wired technologies but also wireless links can be used. In this survey paper, we provide a short overview of autonomous and remote-controlled systems. This paper reviews 5G-related standardization in the maritime domain, covering main use cases and both the role of autonomous ships and that of people onboard. We discuss the concept of a connectivity manager, an intelligent entity that manages complex set of technologies, integrating satellite and terrestrial technologies together, ensuring robust in-ship connections and ship-to-outside connections in any environment. This survey paper describes the architecture and functionalities of connectivity management required for an autonomous ship to be able to operate globally. As a specific case example, we have implemented a research environment consisting of ship simulators with connectivity components. Our simulation results on the effects of delays to collision avoidance confirm the role of reliable connectivity for safety. Finally, we outline future research directions for autonomous ship connectivity research, providing ideas for further work.
