Evaluation and comparison of Bluetooth Mesh networks with existing IEEE 802.15.4 and BLE


On July 18, 2017 the Bluetooth Special Interest Group (SIG) published the Bluetooth Mesh technology. This new addition allows creating many-to-many communication and facilitates communication over longer distances, traversing multiple hops. Mesh networking has been thoroughly studied before in RPL driven IEEE 802.15.4 (ZigBee) networks but has not been practically applicable before in Bluetooth. Given this addition combined with the support and mass deployment of Bluetooth capable devices it is expected to boost Internet of Things (IoT) connectivity.

One of the preliminary questions of this new technology is how it compares to IEEE 802.15.4 based mesh networking and conventional Bluetooth Low Energy (BLE) communication.

Kind of work

Given the recent release of Bluetooth Mesh many manufacturers are still working on their implementation of Bluetooth Mesh. At the time of writing, the “Nordic Semiconductor nRF5 SDK for Mesh” is available. You will check the availability of other Mesh supporting manufacturers/platforms.

A Bluetooth Mesh network consisting of several nodes is set up using a supported platform. The end-nodes can be equipped with sensors and/or actuators like a lamp to represent an IoT environment.

Communication and energy measurements are performed to obtain the range, delay, throughput, power consumption, etc. parameters of a single-hop and multi-hop Bluetooth Mesh network. A comparison is made between Bluetooth Mesh, IEEE 802.15.4 and Bluetooth Low Energy.

Framework of the Thesis

This thesis is proposed in the context of the current IoT projects (EU and Industrial) of the smartnets group.
