IEEE 802.11ad Task Group is currently defining a standard for multi-gigabits per second data rate WLAN connections in the 60 GHz band with a target completion date of 2012. The 802.11n, which operates in 2.4/5 GHz band, guarantees data rate of at least 108 Mbps and coverage of about 50 meters, with a maximum data rate of 600Mbps over relatively short distances. In comparison, 60 GHz band can support...
In this paper we propose a new progressive rate adaptation scheme for uncompressed video over millimeter wave wireless (mmW) in which the video data rate can be adapted to any rate smoothly and with minimal video quality degradation. Two major steps: 1. Progressive pixel differential transformation (PPDT) in which difference values of pixels are compressed and transmitted in a new systematic way for...
We propose a generic algorithm called SFT (Selective Frame Transmission), which is applicable to both pre-encoded and live AV (Audio Video) content streaming, and endeavors to ensure timely delivery of frames to the receiver by selectively dropping certain frames at the transmitter which do not satisfy the end-to-end latency bound. The key idea of SFT is that the end-to-end latency bound includes...
In this paper, we present an analytical model for the approximate calculation of the throughput and end-to-end delay performance in single hop and multihop IEEE 802.11 networks under uniform traffic distribution while accounting for the effect of aggregate interference and capture. We do this using a "major interferer approximation" approach where we approximate the aggregate interference...
