| description | For future heterogeneous networks, network coverage is identified as one of the main challenges. This paper focuses on the spectrum sharing and energy consumption problems with millimeter wave radio over fiber (mmWave RoF) utilized to enhance the coverage of the system. The proposed adaptive scheme includes the following steps. First, the system identifies the users as licensed users that primarily own the specific spectrum and unlicensed users that have to purchase the spectrum. Based on the game theory, the spectrum resource is shared among the eNB and low power nodes (LPNs) with a relatively high benefit. Second, an adaptive sleep schedule scheme is performed to reduce the power cost of some LPNs that are scored under the threshold. Third, an adaptive power allocation scheme is utilized to further reduce the power assumption of the system and does not affect the system demand satisfaction. The simulation results finally show that the proposed resource allocation scheme can achieve improved coverage of the network. |
