Bluetooth Low Energy (BLE) is a wireless protocol that provides low power
communication for battery-driven embedded devices. To achieve the better
tradeoff between energy consumption and communication latency, an advertiser
interval parameter for extending the sleep time of BLE beacon is included
in the protocol. This paper presents a power management mechanism including
the advertising interval initialization for meeting the latency constraint of
broadcasting applications, the advertising interval adaptation for minimizing
the resubmission overhead from the run-time collision, and the scanner-aware
packet scheduler for providing the better quality of service of applications with
multiple rates. The proposed methodology was evaluated through extensive
experiments and the results revealed that the proposed algorithms saved the
energy consumption up to 99% compared with a simple pessimistic setting.
