毫米波多跳D2D网络中转发探测路由的研究

Research of Relay Probing for Millimeter Wave Multi-hop D2D Networks

针对毫米波(device to device,D2D)通信,提出可靠的多跳转发探测包(reliable multi-hop relay probing packet,RMRP)策略,进而构建毫米波D2D路由。转发探测包是建立源节点连通目的节点间的多跳路由的基础。利用从转发节点所接收到的微米波段信号强度估计毫米波信噪比大于阈值的概率,再利用此概率择优选择转发节点,进而最大化从源节点至目的节点路径的吞吐量。仿真结果表明,提出的RMRP策略提高了吞吐量,并控制能耗。

For device to device(D2 D)communication,reliable multi-hop relay probing packet(RMRP)is proposed in this paper.The RMPR is used to construct the millimeter wave D2 D routing.The forwarding probe packet is the basis of multi-hop routing between source nodes and destination nodes.First,the probability that MMW SNR is greater than the threshold is estimated by the signal intensity received from the forwarding node,and then the forwarding node is selected according to the probability to maximize the throughput of the path from the source node to the destination node.Simulation results show that the proposed RMRP strategy improves throughput and controls energy consumption.
