“…Though Bluetooth (IEEE 802.15.1) [1] devices have hold, park, and sniff low activity modes, and the transceiver is designed to minimize power [2], it is still important that an application reduces the total data transmitted, as there is approximately a linear relationship [3,4] between bit rate and energy consumption. A number of authors, for example [4][5][6][7][8], have investigated ways to manage power in a wireless network when streaming video. Although the enhanced data rate (EDR) of Bluetooth version 2.0 [9] now has a peak user payload of 2.2 Mbps (gross air rate 3.0 Mbps), which is the same average rate offered by some implementations of IP-TV, it must still compete with lower power alternatives, such as Wibree from Nokia, intended for button cell batteries, with a gross air rate of 1.0 Mbps.…”

Wireless communication of video, with Bluetooth as an example, represents a compromise between channel conditions, display and decode deadlines, and energy constraints. This paper proposes fuzzy logic control (FLC) of automatic repeat request (ARQ) as a way of reconciling these factors, with a 40% saving in power in the worst channel conditions from economizing on transmissions when channel errors occur. Whatever the channel conditions are, FLC is shown to outperform the default Bluetooth scheme and an alternative Bluetooth-adaptive ARQ scheme in terms of reduced packet loss and delay, as well as improved video quality.
