摘要: In this paper, we propose algorithms for finding the optimum multi-hop routes and corresponding transmit powers that maximize throughput between a pair of device-to-device (D2D) nodes, under constraint on maximum interference caused to cellular network. Our solution involves two steps. first step, determine set feasible D2D links, based constraint. second use celebrated Dijkstra's algorithm find throughput-optimal given nodes scenarios: a) The Fixed Rate Scheme b) Power Scheme. dependency net system parameters such as target SINR is analyzed both schemes, procedure parameter setting proposed. performance illustrated using computer simulations. results show that, depending network topology, significantly higher can be achieved by paths compared single-hop, direct communication.
