This paper considers quality-of-service tradeoffs including compression ratio and overall system latency. The measurements verify that for high speed wireless interfaces such as 802.11b, small changes in compression rates have little effect on system level energy consumption. However, for wireless networks with lower power/bit-rate ratios such as Bluetooth, the choice of bit-rate and compression ratio becomes more important. This paper presents a wireless LAN scheduling algorithm to minimize the energy consumption of a distributed speech recognition front-end on a mobile device.
