ヘテロジーニアスネットワークにおける端末間通信を用いたデータ転送方式

抄録

In this paper, we propose a data relaying method for heterogeneous networks using device to device (D2D) communications. The proposed method uses two communication types (D2D communications and cellular communications) to reduce power consumption of terminals. At first, a source node in a macro cell transmits a data to a relay node in a small cell with D2D communications. Second, the relay node in a small cell transmits the data to a base station (BS) with cellular communications. We implement the proposed method on MATLAB, and confirm that the proposed method can reduce power consumption of terminals in heterogeneous networks. From the computer simulations, the proposed method can achieve 33 percent less power consumption compared with the existing method.
