Abstract - We propose and discuss BE-Mesh-Bluetooth low Energy-Meshed network, a new paradigm for BLE (BluetoothLow Energy) that enables mesh networking among wirelessly interconnected devices, both in a single hop and multi-hop fashion. Starting from the classical Master/Slave paradigm of Bluetooth, we build two new layers based on BLE stack that allow the final user to set-up, in a fast way, the desired network topology while hiding the complexity and low-level details of the BLE stack. We also prototype, as a proof of concept, an open source Android library that implements our communication paradigm and an Android application that allows the exchange of text messages across the mesh network. Last, we demonstrate how BE-Mesh enables Internet access sharing with the whole mesh from a single Internet-connected device.
