SimBetAge: utilizing temporal changes in social networks for pocket switched networks
In this paper, we present SimBetAge, a delay and disruption tolerant routing protocol for highly dynamic socially structured mobile networks. We exploit the lightweight and ego-centric scheme of SimBet routing while at the same time taking the strength and the gradual aging of social relations into account and thereby increase the performance by one order of magnitude, especially in evolving network structures. We explore the model of similarity and betweenness over weighted graphs, and present a simulation on realistic traces from previous experiments, comparing our approach to the original SimBet, Epidemic Routing and Prophet.
