Transcript of "On power and throughput tradeoffs of wi fi and bluetooth in smartphones"

  1. 1. ON POWER AND THROUGHPUT TRADEOFFS OF WI-FI AND BLUETOOTH IN SMARTPHONE’S ABSTRACT This project describes a combined power and throughput performance study of Wi-Fi and Bluetooth usage in smart phones. The work measures the obtained throughput in various settings while employing each of these technologies, and the power consumption level associated with them. In addition, the power requirements of Bluetooth and Wi-Fi in their respective non-communicating modes are also compared. The study reveals several interesting phenomena and tradeoffs. In particular, the paper identifies many situations in which Wi-Fi is superior to Bluetooth, countering previous reports. The study also identifies a couple of scenarios that are better handled by Bluetooth. The conclusions from this study suggest preferred usage patterns, as well as operative suggestions for researcher’s and smart phone developers. This includes a cross-layer optimization for TCP/IP that could greatly improve the throughput to power ratio whenever the transmitter is more capable than the receiver.
