Abstract
A large body of recent flooding-based communication protocol proposals for wire-
less sensor networks exploit concurrent transmissions (CT). Many existing pro-
tocols are designed to run on the IEEE 802.15.4 physical layer. Thus, there is
extensive research on the conditions required for successfully receiving CT over
IEEE 802.15.4. While IEEE 802.15.4 is popular in the research community, Blue-
tooth Low Energy (BLE) has experienced a much wider commercial adoption.
BLE’s ubiquity makes its physical layers an attractive potential alternative for
CT-based protocols.
In this project, we performed an experimental investigation of the conditions
required for the successful reception of CT over IEEE 802.15.4 and the five phys-
ical layer options supported by BLE. We focused on the impact of the choice of
physical layer protocol, differences in packet contents and the time and power
offsets between the transmissions. Our experiments were performed in an ane-
choic chamber using nRF52840 dongles. We tested a wide range of parameter
combinations. To make our results more accessible, we created an interactive
visualisation of our data.
