An auto-configuring mesh protocol with proactive source routing for Bluetooth Low Energy. (2018) - Leon, Julio
The Internet of Things (IoT) is spreading rapidly towards creating smart environments. Wireless sensor networks (WSN) are among the most popular applications discussed in IoT literature, with most of them considering many forms of wireless mesh communications. One of the most available and popular wireless technologies for short-range operations (yet not designed for mesh) is Bluetooth. Literature shows some studies on mesh networks BLE, based on Bluetooth 4.1 (which supports Master/Slave Multirole). Those approaches require more powerful hardware than a simple wireless sensor peripheral. Nonetheless, none address dynamic address allocation and topology mapping for BLE. We propose a new autoconfiguring dynamic address allocation scheme for a BLE Ad-Hoc network, and a network map discovery mechanism that does not require role changing, compatible with BLE 4.0 or later versions.
