- Abstract
- In mobile social networks, mobile users can help each other to disseminate and deliver contents utilizing social relationship (e.g., physical contact). In this paper, we consider content delivery in mobile social networks, where a mobile user (i.e., a content source) transfers not only content, but also energy to an intermediate user (i.e., a mobile content messenger). The messenger uses this energy to store, carry, and forward the content to the destination (i.e., a sink). We particularly address the content messenger selection and wireless energy transfer problem of the content source to determine which messenger to deliver the content and the amount of energy to be transferred to the messenger. We formulate a Markov decision process (MDP) to obtain the optimal policy. The numerical results show clearly the improved performance in terms of higher throughput as compared with a baseline static policy. © 2015 IEEE.
