TSCH Meets BLE: Routed Mesh Communication Over BLE
2023 19th International Conference on Distributed Computing in Smart Systems and the Internet of Things (DCOSS-IoT), 2023Bluetooth Low Energy (BLE) is the prevalent communication protocol for the Internet of Things. However, for time-critical applications requiring time-synchronized multi-hop networks with often multiple node exchanging data at the same time slot, BLE lacks a solution.

DisruptaBLE: Opportunistic BLE Networking
2022 IEEE 47th Conference on Local Computer Networks (LCN), 2022Bluetooth Low Energy (BLE) is the prevalent IoT radio technology and perfectly suited for mobile and battery-driven applications. However, it is not designed for intermittent connectivity and opportunistic networking. Hence, the vast infrastructure that BLE-equipped devices such as smartphones, wearables, and sensors provide, remains untapped, even ...

Commodity-level BLE backscatter
Proceedings of the 19th Annual International Conference on Mobile Systems, Applications, and Services, 2021The communication reliability of state-of-the-art Bluetooth Low Energy (BLE) backscatter systems is fundamentally limited by their modulation schemes because the Binary Frequency Shift Keying (BFSK) modulation of the tag does not exactly match commodity BLE receivers designed for Gauss Frequency Shift Keying (GFSK) modulated signals with high bandwidth

Practical Backscatter with Commodity BLE
ICC 2021 - IEEE International Conference on Communications, 2021Due to extremely low power consumption, backscatter is promising to become general-purpose communication for Internet of Things (IoT) networks. The state-of-the-art BLE backscatter system RBLE can work fully with commodity Bluetooth Low Energy (BLE) devices, however, the communication reliability of RBLE is still limited by its modulation scheme based ...

Survey on Smart Health Management using BLE and BLE Beacons
2019 9th International Symposium on Embedded Computing and System Design (ISED), 2019Advances in Bluetooth technology focusing low energy has brought into action the Bluetooth Smart for wearable devices. Enhancement in Internet of Things due to wearable devices has led to the concept of Ambient Assisted Living (AAL). AAL is mainly devised to assist age old people to carry on daily activities including healthcare without dependencies. A

Reliable Backscatter with Commodity BLE
IEEE INFOCOM 2020 - IEEE Conference on Computer Communications, 2020Recently backscatter communication with commodity radios has received significant attention since specialized hardware is no longer needed. The state-of-the-art BLE backscatter system, FreeRider, realizes ultra-low-power BLE backscatter communication entirely using commodity devices.

Optimal AdvInterval for BLE scanning in different number of BLE devices environment
2016 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS), 2016The Bluetooth Low Energy (BLE) is one of promising technologies widely used for Internet of things (IoT) services because of its low energy consumption. In IoT, BLE gateways should discover surrounding BLE devices in a short time. However, this requirement is difficult to achieve when the number of BLE devices is very large.

Comparison of ZF-BLE and MMSE-BLE in TD-SCDMA system
2001 International Conferences on Info-Tech and Info-Net. Proceedings (Cat. No.01EX479), 2002In this paper, we analyze two kinds of sub-optimal joint detection algorithms-ZF-BLE (zero forcing block linear equalizer) and MMSE-BLE (minimum mean square error block linear equalizer). In theory, we compare their performance by computation and the ability of resisting ISI and MAI.
