“…Recently, the use of a relay with suited channel conditions to deliver messages from the source to multiple destinations in a small area has been addressed, and the capacity region bounds for relay-aided multiple multicast system are provided in [4], demonstrating the benefits of CR. Cooperative multicast has been widely investigated in [30] for performance analysis in terms of improved transmission rate, in [31] for the cognitive aspect, in [32] for the joint use with multiple antenna system and in [33,34] jointly with the adoption of network coding technique.…”

“…The Network Coding (NC) approach, starting from the work of Ahlswede et al [16] for wired networks, has recently gained more attraction in wireless terrestrial networks [17][18][19][20] and can be a key enabling technology for 5G/satellite, mainly for reliable multicast services. NC techniques applied to satellite networks allow: (1) reducing the overall capacity needed to transfer data between peers, saving bandwidth in forward link; and (2) increasing network robustness in the case of residual packet erasures after the channel coding operations performed at the physical layer.…”

Satellites can provide strong value-add and complementarity with the new cellular system of the fifth generation (5G) in cost-effective solutions for a massive number of users/devices/things. Due to the inherent broadcast nature of satellite communications, which assures access to remote areas and the support to a very large number of devices, satellite systems will gain a major role in the development of the Internet of Things (IoT) sector. In this vision, reliable multicast services via satellite can be provided to deliver the same content efficiently to multiple devices on the Earth, or for software updating to groups of cars in the Machine-to-Machine (M2M) context or for sending control messages to actuators/IoT embedded devices. The paper focuses on the Network coding (NC) techniques applied to a hybrid satellite/terrestrial network to support reliable multicast services. An energy optimization method is proposed based on joint adaptation of: (i) the repetition factor of data symbols on multiple subcarries of the transmitted orthogonal frequency division multiplexing (OFDM) signal; and (ii) the mean number of needed coded packets according to the requirements of each group and to the physical satellite links conditions.

“…Successive relay techniques [9] are analyzed to improve the spectral efficiency of HD relays, in which a pair of relays is selected, and while one relay receives data from the source, the other transmits the previously received data to the destination. The use of a buffer at the relay nodes, "buffer-aided relaying methods", as in [10][11][12][13][14][15], increases the spectral efficiency with respect to HD relaying without a buffer. This approach allows for selecting the best HD buffer-aided relay among the various relay-destination links (opportunistic relaying schemes), to transmit the data if the channel conditions are good or buffer it otherwise, as in max-max relay selection by Ikhlef et al [16] or the max-link relay selection scheme by Krikidis et al [17].…”

Abstract:The increasing use of social networks such as Facebook, Twitter, and Instagram to share photos, video streaming, and music among friends has generated a huge increase in the amount of data traffic over wireless networks. This social behavior has triggered new communication paradigms such as device-to-device (D2D) and relaying communication schemes, which are both considered as strong drivers for the next fifth-generation (5G) cellular systems. Recently, the social-aware layer and its relationship to and influence on the physical communications layer have gained great attention as emerging focus points. We focus here on the case of relaying communications to pursue the multicast data dissemination to a group of users forming a social community through a relay node, according to the extension of the D2D mode to the case of device-to-many devices. Moreover, in our case, the source selects the device to act as the relay among different users of the multicast group by taking into account both the propagation link conditions and the relay social-trust level with the constraint of minimizing the end-to-end content delivery delay. An optimization procedure is also proposed in order to achieve the best performance. Finally, numerical results are provided to highlight the advantages of considering the impact of social level on the end-to-end delivery delay in the integrated social-physical network in comparison with the classical relay-assisted multicast communications for which the relay social-trust level is not considered.
