Towards High Throughput Wireless Network with Directional Antenna
Abstract
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 TCP throughput improvement, compared to the conventional scheme that only uses one AP mounted with one omni-directional antenna.
