A SURVEY OF BLE MESH NETWORKS

Abstract

Important momentum was obtained by Bluetooth Low Energy (BLE). BLE's initial architecture, however, centred on star topology networking, which reduces the extent of network coverage and precludes diversity of end-to-end routes. Some rival technologies, on the other hand, resolve those limitations by endorsing the topology of the mesh network. Academia, business, and standards implementation organizations have been developing technologies to make BLE mesh networks for these purposes. The literature, however, lacks a consolidated perspective on this emerging field. This paper explores state-of-the-art BLE mesh networking comprehensively. Second, we have taxonomy of solutions from the BLE mesh network. We then evaluate the solutions, explaining the spectrum of methods that exploit existing BLE features to enable BLE mesh networks. We describe main features of solutions for BLE mesh networks and address their benefits and disadvantages. Finally, we are highlighting transparent problems at present.
