There’s a new research paper by Seyed Mahdi Darroudi and Carles Gomez of Department of Network Engineering, Universitat Polit\u00e8cnica de Catalunya, Castelldefels 08860, Spain on Bluetooth Low Energy Mesh Networks: A Survey<\/a>\u00a0(pdf).<\/p>\n

It gives a consolidated view of mesh Bluetooth LE networks. It explains how Bluetooth LE was originally designed for a star network topology with limited range. While Bluetooth 5 increases the range, there are still scenarios that require longer range which can be solved by networking devices into a mesh. The paper covers current standard, academic and proprietary mesh networks and discusses the merits of flooding-based vs routing-based solutions.<\/p>\n

One omission is FruityMesh<\/a> that isn’t discussed in the paper. Another omission is discussion of battery\/power use. One of the main features of Bluetooth LE is low power. This comes about because devices only transmit for about 1ms every period, where a period is typically 100ms to 1s. Once devices have to talk to each other, the transmission time goes up with a consequent increase of battery power. In practice, battery driven mesh networks end up having high latency and\/or very low data throughput in order to conserve power.<\/p>\n

Another consideration is what goes on top of Bluetooth LE mesh networks. The application layer is often left to the developer. For example, facilities to manage meshes of iBeacon\/Eddystone beacons don’t exist. The application level ends up being proprietary and complex.<\/p>\n","protected":false},"excerpt":{"rendered":"
