Nevertheless, in the dynamic/mobile environment, the poor computing ability and storage capability of a single node make it difficult to share the content among nodes. In order to enhance the capability of the mobile terminals and improve the efficiency of content distribution, a cloud-assisted architecture to offload the heavy computation load from the mobile nodes to the cloud was put forward. Furthermore, a Multi-Tree Structure of Internal Node Disjoint (MTSIND) data transfer topology was proposed, in which their internal nodes are disjoint, thus each node can take part in the content delivery tasks. Finally, an exclusive-OR (XOR) network coding method based on vertex coloring problem was established to reduce the number of transmissions and power consumption. Simulation and numerical results were provided to support the analyses and results. Results show that the content distribution mechanism can reduce the total number of the data packets and the energy consumption. The study proves that the research of content distribution mechanism on MP2P has a great significance on reducing the number of data transmissions, lowering the power consumption of terminals and increasing the resource utilization of mobiloe nodes
