论文摘要
在房屋和办公室等室内地区，多个设备的高吞吐量迅速成为必要。即使装有Omni方向天线的访问点（AP）可以覆盖整个房间，但它无法在整个房间内提供高通量的连接。因此，我们提出，\ emph dirf是一种基于定向天线的无线家庭网络，旨在在室内部署的室内高吞吐量，并具有密集部署的方向性AP。 \ Emph Dirf由基于位置的AP选择算法组成，该算法可以减少由频繁的AP开关引起的延迟积累，以及一个下行链路数据包调度程序，可以减少AP开关期间的下链接数据包重新启动。我们用六个商业AP实施和评估\ Emph Dirf，每个AP都与单个定向天线连接。我们的实验表明，与仅使用一个使用一个Omni方向天线的AP相比，\ emph dirf实现了$ 3.16 \ times $ tcp吞吐量的改进。
In indoor areas such as homes and offices, high throughput communication for multiple devices is quickly becoming a necessity. Even though an access point (AP) mounted with an omni-directional antenna can cover a whole room, it cannot provide connections with high throughput throughout the room. Therefore, we propose, \emph DiRF, a directional antenna based wireless home network designed to achieve high throughput in indoor areas with densely deployed directional APs. \emph DiRF consists of a position based AP selection algorithm which can decrease latency accumulation caused by frequent AP switching, and a downlink packet scheduler which can reduce the downlink packet retransmissions during AP switching. We implement and evaluate \emph DiRF with six commercial APs, each connects with a single directional antenna. Our experiments show that \emph DiRF achieves a $3.16\times$ TCP throughput improvement, compared to the conventional scheme that only uses one AP mounted with one omni-directional antenna.
