先前关于低功耗蓝牙（BLE）的理论发现延迟的研究已经在专用的BLE芯片上系统（SoC）上反复验证，但在多无线电SoC（如智能手机中的SoC）上的验证程度要小得多。在本文中，我们评估邻居发现延迟和能源消耗的各种参数下的Android智能手机API 24蓝牙4.2。我们进一步研究了并发Wi-Fi流量对广告信道上的能耗和BLE分组接收的影响。我们发现，平均发现延迟可以与最先进的模型预测的结果相媲美，同时在广告时间间隔内表现出更高的可变性。能耗偏离所选模型的预测，Wi-Fi干扰测试显示，当干扰流量涉及BLE扫描活动时，对能耗和发现延迟的影响要大得多。
Previous studies concerning theoretical discovery latency for Bluetooth Low Energy (BLE) have been repeatedly validated on dedicated BLE Systems on Chips (SoCs), but to a much lesser extent on multi-radio SoCs such as those found in smartphones. In this paper, we evaluate neighbor discovery latency and energy consumption across various parameters available on an Android smartphone under API 24 for Bluetooth 4.2. We further investigate the effect of concurrent Wi-Fi traffic on energy consumption and BLE packet reception over advertising channels. We found that average discovery latency can be comparable to what state of the art models predict, while exhibiting higher variability across advertising intervals. Energy consumption deviates from that predicted by the chosen models and Wi-Fi interference tests show a much greater impact on energy consumption and discovery latency when interference traffic involves the BLE scanning activity.
