摘要

IEEE 802.11ah and Bluetooth Low Energy (BLE) are candidates to become key technologies for many Internet of Things (IoT) applications. In this paper, 802.11ah and BLE technologies are evaluated and compared in a home automation scenario. The selected use case includes battery powered sensors, which generate traffic, and mains powered actuators, which consume traffic, connected through a central gateway. The performance is assessed in terms of service ratio, delay and activity factor of the transceivers. Results show that both technologies are suitable for the reference use case scenario. 802.11ah benefits from a higher throughput and lower delay jitter, whereas BLE sensors show lower activity factors and a longer battery lifetime is expected. The analysis is conducted for both fixed and variable traffic load. The performance of BLE results to be more sensitive to an increase of the traffic load with respect to 802.11ah. Eventually, the limitations of the current scenario are illustrated and alternative setups are discussed.
