Abstract:
Device-to-Device (D2D) communication has become a promising technology to enhance the performance of cellular networks. The major challenge for resource sharing in D2D networks lies in the co-interference between cellular users and the originated D2D connections. In addition, power allocation for D2D connections and cellular users sharing the same spectrum is also a problem for these networks. In D2D caching networks, caching contents at users' devices can significantly reduce large network headaches. This becomes a promising solution for controlling limited resources. Maximizing the cached portions delivered to users using D2D communications requires combined consideration for guaranteed D2D channels and their allocated power. In this paper, a joint optimization problem of caching content caching delivery with resource and power allocation awareness to improve the performance of D2D caching networks is presented. We aim to enhance the performance of such networks by maximizing the overall sum rate of D2D and cellular users. An optimization problem for sum rate is formulated under the constraint of power requirements and Signal-to-Interference plus Noise Ratio (SINR). The proposed optimization problem will be solved using an optimization algorithm by jointly optimize channel and power allocation. The simulation results show that the performance of the optimal scenario with effectively selecting suitable locality ratio and D2D power optimization can lead to valuable gains in the sum rate. © 2019 IEEE
