User generated content in mobile social networks are typically short-lived in time and space. Opportunistic communication as such is not suitable for user generated content dissemination in mobile social networks due to high content delivery delays. To reduce these delays, we propose a hybrid content dissemination strategy, which makes use of available low-cost networking infrastructure to replicate content on smartphones, and leverages these replicators to propagate the content to others via opportunistic communication. Using trace-driven simulations, we show that the content can be delivered to all users in a mobile social network within time bounds by replicating content using infrastructure to only 10% of the consumers. Furthermore, due to the high rate of timely content delivery, the proposed hybrid content dissemination scheme ultimately saves approximately 60% of the infrastructure bandwidth usage compared to traditional mobile peer-to-peer dissemination in a general MSN environment. In addition, the replication strategies proposed in the paper are robust enough to deliver the same performance even with low collaboration of consumers for replication.
