It has been widely acknowledged that future networks need to provide significantly more capacity than nowadays' ones in order to deal with the increasing traffic demands of the users. Particularly in regions where optical fiber are unlikely to be deployed due to economical constraints, this is a huge challenge. One option to address this issue is to complement existing narrow-band terrestrial networks with additional satellite connections. Satellites cover huge areas and recent developments have considerably increased the available capacity, while the cost are decreasing. However, geostationary satellite links have significantly different link characteristics than most terrestrial links, mainly due to the higher signal propagation time, which often renders them not suitable for delay intolerant traffic. This article surveys the current state-of-the-art of satellite and terrestrial network convergence. We mainly focus on scenarios in which satellite networks complement existing terrestrial infrastructures, i.e. parallel satellite and terrestrial links exist, in order to provide high bandwidth connections while ideally achieving a similar end user Quality-of-Experience as in high bandwidth terrestrial networks. Thus, we identify the technical challenges associated with the convergence of satellite and terrestrial networks and analyze the related work. Based on this, we identify four key functional building blocks, which are essential to distribute traffic optimally between the terrestrial and the satellite networks. These are the Traffic Requirement Identification function, the Link Characteristics Identification function as well as the Traffic Engineering function and the Execution function. Afterwards, we survey current network architectures with respect to these key functional building blocks and perform a gap analysis, which shows that all analyzed network architectures require adaptations to effectively support converged satellite and terrestrial networks. Hence, we conclude by formulating several open research questions with respect to satellite and terrestrial network convergence.

“…Satellite communications on the move (SOTM) systems have become an essential part of commercial and military communications because they offer the high-speed wireless link to moving vehicles such as maritime vessels, trains, and land vehicles through a satellite [1][2][3]. In the SOTM system, the antenna of the SOTM terminal, which is equipped with an active control system and an inertial navigation system is pointed to the satellite.…”

“…Furthermore, an FEC technique such as channel coding that is applied in the physical layer of the satellite communications only corrects data corruption due to the noise and the interference. It cannot recover packets lost owing to the channel blockage in the SOTM network because of its fixed time diversity and fixed amount of protection [1].…”

In this paper, we propose a fully reliable file-transfer framework with application layer forward error correction (AL-FEC) in satellite communications on the move (SOTM) systems. In particular, the proposed framework uses a two-way acknowledgement (ACK) exchange mechanism. The proposed framework is implemented into a performance-enhancing proxy to minimize the system change. Furthermore, we analyze the file-transfer time of the proposed framework by Markov chain. The analysis results show that the proposed framework outperforms TCP in terms of the file-transfer time and the goodput. Furthermore, in the transfer of a large-sized file, the overhead of the proposed AL-FEC mechanism is small in terms of the resource efficiency.

“…Satellite communication is considered to be crucial in the ubiquitous communication system as a result of its wide area coverage. In order to achieve a real sense of worldwide communication, satellite, sometimes, is the only solution for MANET to communicate with other parts of the world and bridge the digital divide [1] [2]. Therefore, satellite is not only utilized as a component of an alternative routing path but also considered as part of integrated MANET-Satellite system.…”

Abstract-A mobile ad hoc network (MANET) is a selfconfiguring infrastructure-less network. Taking advantage of spontaneous and infrastructure-less behavior, MANET can be integrated with satellite network to provide world-wide communication for emergency and disaster relieve services and can also be integrated with cellular network for mobile data offloading. To achieve different purposes, different architecture of integrated system, protocols and mechanisms are designed. For emergency services, ubiquitous and robust communications are of paramount importance. For mobile data offloading services, emphasis is amount of offloaded data, limited storage and energy of mobile devices. It is important to study the common features and distinguish of the architecture and service considerations for further research in the two integrated systems. In this paper, we study common issues and distinguish between two systems in terms of routing protocol, QoS provision, energy efficiency, privacy protection and resource management. The future research can benefit from taking advantage of the similarity of two systems and address the relevant issues.
