Abstract
In mobile social network service (MSNS) environment, users can establish a group relying on some relationships and share services within a group or among different groups. When the mobile devices provide services for a user, some service transmission paths will fail because of device movement or failure, and the user cannot receive required services. Recovering the service quickly and efficiently is the main problem of this paper. This paper presents a new service transmission and recovery strategy based on cluster in MSNS. Establishment mechanism of recovery point is adopted in the strategy. The recovery point is able to save and maintain the service data received from the service provider. When the service transmission fails, the upstream recovery point can directly resend the service data to its downstream recovery point. Simulation results show that this strategy can save the transmission time and improve the probability of successful transmission.
Keywords: Cluster, communication, group. mobile social network service, recovery, transmission.
