摘要

Device-to-Device (D2D) communication represents an innovative technology that improves throughput, spectrum efficiency and reduces the latency in wireless network. There is huge demand for the wireless services which defaults to spectrum scarcity and D2D communication is the viable solution to go for. In D2D communication, cellular resources are shared to D2D users which creates the co-channel interference between them. Therefore, attention is required to mitigate the interference and efficiently distribute the resource and power to users so that system performance is improved. In this paper, macro cell and small cells are deployed with cellular and D2D users to form the Heterogeneous Network (HetNet). We introduce Mode Selection-Sequentially Search High Throughput Algorithm (MSSSHTA) to re-use cellular resources to D2D users effectively and protecting the Quality of Service (QoS) of the cellular customers. Then, optimization is performed through Genetic Algorithm (GA) and allocate the transmit powers to D2D and cellular users to minimize the interference in the network. Proposed algorithms are compared with the existing methods and results are assessed with respect to throughput, battery utilization and energy efficiency of the network.
