Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: By caching files at users, content delivery traffic can be offloaded via device-to-device (D2D) links if a helper user is willing to transmit the cached file to the user who requests the file. In practice, the user device has limited battery capacity, and may terminate the D2D connection when its battery has little energy left. Thus, taking the battery consumption allod by the helper users to support D2D into account introduces a reduction in the possible amount of offloading. ,  investigate the relationship beten offloading gain of the system and energy cost of each helper user. To this end,  introduce a user-centric protocol to control the energy cost for a helper user to transmit the file. Then,  optimize the proactive caching policy to maximize the offloading opportunity, and optimize the transmit por at each helper to maximize the offloading probability. Finally,  evaluate the overall amount of traffic offloaded to D2D links and evaluate the average energy consumption at each helper, with the optimized caching policy and transmit por. Simulations show that a significant amount of traffic can be offloaded even when the energy cost is kept low.
