Abstract
In this paper, we study the directional data transmission of multi-cells. In a high-density cell scenario, if nodes of multi-cell perform data transmission randomly in the Scheduling Period (SP) phase, there may be a large interference between the links of cells using the same frequency. In order to reduce the interference, improve the throughput of the network, and reduce the delay of the network and packet loss rate, we propose a multi-cell cooperative transmission scheme. In our proposed scheme, one cell is set as the primary cell, and one cell is the secondary cell, and a special new frame is proposed. When the nodes of the primary cell starts SP, the data sender of the cell sends the frame to synchronize between cells. The node of the other cell that received the frame performs data transmission at the appointed time point. Through our proposed scheme, the impact of other cells transmitting data on the acknowledgement (ACK) of the cell is greatly reduced. The simulation results show that the proposed scheme improves the anti-interference performance of the network including improving the network throughput and reducing the packet loss rate and packet transmission delay of the network compared with AP Clustering.
