NDN meets BLE: A Transparent Gateway for Opening NDN-over-BLE Networks to your Smartphone

Bluetooth Low Energy (BLE) has seen a remarkable adoption and it is widely available on a variety of devices, such as modern PCs, smartphones, and battery driven sensors. A great number of software tools exist already that implement sensor-generic Bluetooth profiles. On the lower end, BLE features a robust energy efficient link layer. The technology, however, lacks multi-hop capabilities. In this demo we showcase a constrained NDN network that utilizes BLE L2CAP connections for robust communication. We enable multi-hop topologies and set up an NDN-to-BLE gateway in order to reuse existing BLE applications that expect GATT payloads.
