Abstract
This paper introduces a block-based form of rateless channel coding that minimizes energy consumption by reducing the overhead and latency from channel coding. Consequently, results from a Bluetooth (IEEE 802.15.1) wearable wireless network for augmented reality (AR) show a consistent reduction in energy consumption compared to Bluetooth FEC schemes. AR relies on video transmission across a wearable network. Block-based rateless coding resulted in around 5 dB improvement compared to block-based FEC in video quality at a head-mounted display in the face of worsening channel conditions. System modeling took into account cross-traffic resulting from biosensors that moderate the AR display according to the cognitive load of the wearer.
