Routings in mobile opportunistic social networks (MOSNs) are challenging problems due to their dynamic network structures. This paper finds that MOSNs exhibit a nested core-periphery hierarchy (NCPH). In the NCPH, few active nodes with large weighted degrees are the network core, while the network peripheries are composed of inactive nodes with small weighted degrees. “Nested” indicates that the NCPH...
In this paper, an up-and-down routing protocol is proposed for mobile opportunistic social networks, which exhibit a nested core-periphery structure. In such a network, a few active nodes with large weighted degrees form the network core, while the network peripheries are composed of many inactive nodes with small weighted degrees. By nested, it means that the core-periphery structure is preserved,...
