In this paper, the problems facing designers of peer-to-peer instant messaging protocols, specifically those intended to run over mobile ad-hoc networks, are discussed. In particular, the challenges of identity management and presence dissemination are addressed, with an efficient and user-friendly protocol described that solves them. As a side effect, a form of social network mining is offered that...
In mobile social networks (MSN) individuals with similar interests or commonalities connect to each other using the mobile phones. MSN are special kind of ad-hoc networks in which wireless connectivity (i.e. encounters and re-encounters) with social peers is predictable. Most of the recent research proposes routing framework to exploit these predictable patterns to identify the best information carriers...
In the context of social relationships, cellular phones and their contacts construct a social network by nature. In this paper, we propose VegaNet, a peer-to-peer overlay network enhancing the performance and reliability of DHT routing using social links. The nodes in VegaNet are identified by the users' social identity, and it is structured by underlying DHT overlay exploiting social identities and...
