Abstract: In mobile social networks (MSNets), the packet is propagated through the intermittently connectivity which is established when two human-carried wireless-enabled devices are within communication range of each other. In order to use the intermittently connectivity to disseminate the packet, a seed-based data dissemination (SDD) algorithm was proposed in campus MSNets. The main idea is to choose a seed node for each community and use the seed node in data dissemination. Simulations show that, compared with the Epidemic algorithm, the publish/subscribe system and social groups based routing, SDD algorithm could reduce network overhead significantly, and near to the maximum delivery ratio obtained by the Epidemic algorithm.

Key words: data dissemination, student schedule, network overhead, mobile social networks
