Using ‘word of mouth’ to find community structure in an online IMS system

Presence is a feature that is used widely in lots of system, especially in IMS. The presence system in IMS also provides application developer and end user with a chance to new style applications. But the presence system in IMS has some problems. Previous researches show that the traffic increases rapidly with the presentity number grows. In this study, we would treat the system in a different way by introducing some social networking concepts to the architecture. Moreover, we would focus on how to apply and generate community in the dynamic and online environment. A word of mouth marketing principle would be used to model the community generating procedure. The presence system would works like a marketing environment. Experiment with simple math analysis show this approach is effective for distributed community generating.
