The Internet, and propose an efficient and scalable server-toserver overlay architecture called Presence Cloud to improve the efficiency of mobile presence services for large-scale social network services. The buddy-list search problem in distributed presence server architecture; the design of PresenceCloud in detail. The complexity analyses of PresenceCloud, the mesh-based scheme and the DHT-based scheme are presented. The performance results of the three approaches are detailed, performance issues related to PresenceCloud, contains some concluding remarks.
