Abstract EN
Caching content by users constitutes a promising solution to decrease the costly transmissions with going through the base stations (BSs).
To improve the performance of in-network caching in device-to-device (D2D) communications, caching placement and content delivery should be jointly optimized.
To this end, we jointly optimize caching decision and content discovery strategies by considering the successful content delivery in D2D links for maximizing the in-network caching gain through D2D communications.
Moreover, an in-network caching placement problem is formulated as an integer nonlinear optimization problem.
To obtain the optimal solution for the proposed problem, Lagrange dual decomposition is applied in order to reduce the complexity.
Simulation results show that the proposed algorithm has a near-optimal performance, approaching that of the exhaustive search method.
Furthermore, the proposed scheme has a notable in-network caching gain and an improvement in traffic offloading compared to that of other caching placement schemes.
