Abstract:

Due to its advantages in service flexibility, scalable video coding (SVC) has been widely used in Device-to-Device (D2D) network communication, which is an effective network technology in the fifth generation (5G) communication network. However, duo to the limited capacity of mobile device, the uninterrupted transmission communication is difficult to be maintained, which needs to be solved urgently. Therefore, in this paper, we introduce the maximum offloading traffic and energy cost ratio to estimate service performance and propose a heuristic algorithm based on the greedy strategy to maximize the offloading traffic because of the NP-hardness of the cache placement problem for SVC. Then, we improve the energy efficiency over D2D link by optimizing the transmission power. Finally, a series of detailed simulation experiments are conducted to analyze the relationship between offloading traffic and energy cost, which demonstrates that a tradeoff exists between the significant amount of traffic and approving energy efficiency.
