Abstract: To address the high-bandwidth and low-latency requirements in mobile social networks (MSNs), this paper suggests a link-based congestion management mechanism, to adjust the source rate of each stream, introduces a prioritized flow management mechanism, defines a concept "stress weight" and its associated utility function. Additionally, we addressed the problem of single sign-on authentication with various third party SNs. Simulation results show that this mechanism works significantly better than the alternative approach, and the authentication mechanism has good scalability.

Key words: computer application, multicast congestion control, stress weight, social network based live sharing, flow management
