In response to the issue of mobile terminal heterogeneity in the existing Peer-to-Peer (P2P) data sharing network, an energy-aware P2P data sharing mechanism in heterogeneous mobile terminal named EADS was proposed, which enabled terminals to determine the types of end-user devices with introducing an energy-aware module to predict residual energy of these end-user devices. On this basis, the mechanism adjusted data sharing strategy dynamically in accordance with the changes of network environment. The simulation results demonstrate that EADS achieves significant performance improvement, in terms of energy utilization efficiency, balance load, as well as data sharing time, thus enhancing the success rate of data distribution. On the premise of maintaining high availability of files, average energy consumption has been reduced up to 15%.
