Among the various wireless technologies available today,Bluetooth stands out as the most promising for usein low-power sensor networks. This is especially true forlarge networks of sensors with low data rates, where Bluetooth'slow power Hold, Sniff, and Park modes could beutilized during periods of low activity to reduce power con-sumption.One way that these modes can be exploitedto reduce energy consumption is by using an intelligentpolling scheme to control intra-piconet traffic. We introducea novel polling algorithm called Adaptive SharePolling (ASP) that is designed to perform well when thenetwork consists of sources sending short data packets atconstant rate that may fluctuate over time. In ASP, thescheduler at the master implicitly learns the share of thebandwidth that needs to be allocated to each of the slavesin order to meet the latency and/or power requirements ofthe application. Our simulation results show that significantpower savings can be achieved in slaves whose datarates do not approach capacity of a Bluetooth piconet, andin masters when the composite data rate of the piconet doesnot approach capacity.
