| Summary: | Title screen Device-to-device (D2D) communication is a promising technology for 5G networks, providing high data rates, increased spectral and energy efficiency, and reduced end-to-end delay and transmission power. However, in current cellular systems, the performance of cell edge devices suffers when multimedia content is directly uploaded toward the base station side due to poor link quality. This requires a greater number of resource blocks and additional upload time, thus degrading the quality of service. To reduce the number of resource blocks and upload time, this paper proposes an efficient resource management scheme that exploits D2D communication in the uplink case. This scheme consists of two phases. In the first phase, in the case of poor link quality, a novel relay selection scheme is used in the multihop (two-hop) communication strategy; in the second phase, an effective new resource allocation scheme is used in multihop communication. This scheme minimizes packet loss, upload time, and number of resource blocks, whereas it increases the throughput of the network. Simulation result demonstrates the superiority of the proposed scheme over other schemes in the literature. Режим доступа: по договору с организацией-держателем ресурса |
