Cooperative multicast aided picocellular hybrid information dissemination in mobile social networks: Delay/energy evaluation and relay selection

Abstract

Abstract-A novel hybrid information dissemination scheme is proposed for picocellular systems. At the first stage of our scheme, some of the mobile users (MUs) successfully receive the information of common interest via BS-aided multicast. At the second stage, the information is cooperatively multicast (comulticast) by the information owners (IOs) in a self-organized ad hoc network until all the MUs receive it. Since limited resources are provided for the second stage of the spontaneous co-multicast, some of the IOs are appointed for relaying the information to the hitherto unserved MUs. Several relay selection protocols are conceived for the sake of improving the performance of our hybrid information dissemination scheme. The simulation results demonstrate that our scheme may reduce the average dissemination delay and the average energy dissipation by 20% and 70%, respectively, when compared to the conventional BS aided single-hop multicast. Furthermore, we demonstrate that relying on the IOs associated with the best links plays a crucial role in facilitating spontaneous information dissemination.

Bridging the Social and Wireless Networking Divide: Information Dissemination in Integrated Cellular and Opportunistic Networks

“…As shown in our previous work [57], various distance-based and transmission rate-based centralities may be conceived, such as the Shortest-Longest-Distance centrality, the Shortest-Shortest-Distance centrality, and the Shortest-Sum-Distance centrality as well as the Highest-Sum-Rate centrality. The simulation results of [57] demonstrate the advantage of these centrality based resource scheduling schemes over the traditional RR regime.…”

“…The tools of SNA can also be exploited for further improving the information dissemination performance of integrated cellular and small-scale opportunistic networks, as we detailed in [57]. The rest of this treatise is organised as follows.…”

Socially aware integrated centralized infrastructure and opportunistic networking: a powerful content dissemination catalyst

“…However, for the sake of further improving the attainable performance of the CoCI dissemination, we could carefully select the most suitable CoCI owners for forwarding the CoCI to the hitherto unserved MUs during the next stage of CoCI dissemination. As a result, we should evaluate the potential impact of a CoCI owner on all the unserved MUs with the aid of social network analysis tools [8]. During the second stage of the cooperative multicast aided CoCI dissemination portrayed in Fig.…”
