In sparse mobile social networks, the moving activity of nodes always happen in a specific area, which corresponds to some specific community. How to guarantee the higher packet delivery ratio while reducing forwarding delay in such networks, is a challenging issue and has not been widely investigated yet. Recently, additional super-node was introduced to ferry packets between the isolated areas....
In traditional delay tolerant networks (DTNs), there exists a potential assumption that the nodes are willing to help others for packet forwarding. However, in the real application scenarios, such as civilian DTNs, selfish behaviors always widely exist. Therefore, the assumption that nodes are cooperative is not realistic in all applications. Currently, most of the existing incentive mechanism focuses...
Peer-to-peer file sharing techniques are efficient and popular ways to distribute network media contents. Aiming to improve the accessibility of media contents from mobile devices, we introduce peer-to-peer file sharing technique into delay tolerant networks (DTNs), which are formed solely by highly mobile devices and which distribute files utilizing the mobility of humans and vehicles. We first investigate...
