  • bluetooth low energy Mesh Networks: A Standards Perspective
    IEEE Communications Magazine, 2020
    Co-Authors: Seyed Darroudi, Carles Gomez, Jon Crowcroft
    Abstract:

    bluetooth low energy (BLE) mesh networking is an emerging technology domain that promises an important role in the Internet of Things. Significant market opportunities for BLE mesh networking have motivated the recent development of two different BLE mesh networking standards, bluetooth Mesh and 6BLEMesh, produced by the bluetooth SIG and IETF, respectively. These two standards follow different technical approaches. In this article, we present the main features of bluetooth Mesh and 6BLEMesh, and investigate their performance characteristics and trade-offs.

  • bluetooth low energy Mesh Networks: A Survey
    Sensors, 2017
    Co-Authors: Seyed Darroudi, Carles Gomez
    Abstract:

    bluetooth low energy (BLE) has gained significant momentum. However, the original design of BLE focused on star topology networking, which limits network coverage range and precludes end-to-end path diversity. In contrast, other competing technologies overcome such constraints by supporting the mesh network topology. For these reasons, academia, industry, and standards development organizations have been designing solutions to enable BLE mesh networks. Nevertheless, the literature lacks a consolidated view on this emerging area. This paper comprehensively surveys state of the art BLE mesh networking. We first provide a taxonomy of BLE mesh network solutions. We then review the solutions, describing the variety of approaches that leverage existing BLE functionality to enable BLE mesh networks. We identify crucial aspects of BLE mesh network solutions and discuss their advantages and drawbacks. Finally, we highlight currently open issues.

  • Transmission of IPv6 Packets over bluetooth low energy
    2013
    Co-Authors: Markus Isomaki, Johanna Nieminen, Zach Shelby, Teemu Savolainen, Carles Gomez, Basavaraj Patil
    Abstract:

    bluetooth low energy is a low power air interface technology defined by the bluetooth Special Interest Group (BT-SIG). The standard bluetooth radio has been widely implemented and available in mobile phones, notebook computers, audio headsets and many other devices. The low power version of bluetooth is a new specification that enables the use of this air interface with devices such as sensors, smart meters, appliances, etc. The low power variant of bluetooth is currently specified in the revision 4.0 of the bluetooth specifications (bluetooth 4.0). This document describes how IPv6 is transported over bluetooth low energy using 6lowPAN techniques.

  • Venom: a visual and experimental bluetooth low energy tracking system
    Proceedings of the 13th ACM Conference on Security and Privacy in Wireless and Mobile Networks, 2020
    Co-Authors: Guillaume Celosia, Mathieu Cunche
    Abstract:

    The bluetooth low energy (BLE) protocol is being included in mobile devices such as smartphones, headphones and smartwatches. As part of the BLE service discovery mechanism, devices announce their presences by broadcasting radio signals called advertisement packets that can be collected with off-the-shelf hardware and software. To avoid the risk of tracking based on those messages, BLE features an address randomization mechanism substituting the device MAC address with random temporary pseudonyms. However, the payload of advertisement packets still contains fields that can negate the randomization mechanism by exposing static identifiers. In this paper, we present Venom (Visual and ExperimeNtal bluetooth low energy tracking systeM), an experimental tracking platform aiming to raise public awareness about physical tracking technologies and experiment privacy-preserving mechanisms. Venom tracks users by collecting advertisement packets broadcasted by their BLE-enabled devices, and displays related information.

  • BLEmesh: A Wireless Mesh Network Protocol for bluetooth low energy Devices
    2015 3rd International Conference on Future Internet of Things and Cloud, 2015
    Co-Authors: Hyung Sin Kim, Jungyub Lee, Ju Wook Jang
    Abstract:

    bluetooth low energy is a highly adopted and anticipated communication solution for the Internet of Things. However, the restriction of data communication topology to point-to-point, limited range of communications, and the lack of IP support make bluetooth low energy less attractive for Internet of Things applications. In Dec. 2014, the bluetooth SIG standardized the Internet Protocol Support Profile to support the exchanging of IPv6 packets between devices over bluetooth low energy. Still, a mesh networking protocol for multi-hop support is needed for it to overcome the limitations due to short range and restricted topology. This paper introduces Blemish, a wireless mesh network protocol which utilizes the broadcasting capability of wireless transmissions. We identify the available data payload using bluetooth low energy Generic Access Profile -- Non-connectable Advertisement Data for different number of nodes and packets to send in a batch. Then we compare BLEmesh with conventional routing method and flood routing method. Our preliminary evaluation results show that the number of transmissions by BLEmesh is significantly smaller compared to its competitors for some selected network configurations, reducing the aggregated energy consumption within the mesh network.
