摘要 Delay Tolerant Networks (DTNs) use the "Store-Carry-then-Forward" approach to deliver the message to the destinations. It relies on the intermittent link that occurs when two nodes contact with each other due to mobility. In this paper, we propose a three-phase algorithm (SFMS: Spray and Forwarding scheme with Message Scheduling) that integrates the concepts of flooding-based and forwarding-based protocols, and considers message priority. The idea of SFMS is to periodically predict the contact popularity and contact association among nodes, such that we can determine the fast message spraying and efficient forwarding strategy. Furthermore, we propose a message scheduling mechanism to enhance the resource allocation. Simulation results show that our scheme has a better performance for delivering message. Besides, it also achieves a differential delivery performance for different priorities of message while maintaining a better resource allocation. © 2013 ACM.
