Bringing Cross-Technology Communication to Smartphones (NES Group)

Bluetooth Low Energy (BLE) and IEEE 802.15.4 are the two most widespread wireless technologies used for the Internet of Things. Due to the heterogeneity of those technologies, it is not possible for co-existing IoT devices to communicate with each other or to share information. In order to allow a communication between devices employing incompatible wireless technologies, a mechanism called Cross-Technology Communication (CTC) can be used which aims to use specific interference patterns to convey information between different wireless standards.

We have developed a CTC scheme that allows a direct communication between BLE and IEEE 802.15.4 devices by encoding information into precisely timed energy bursts. The scheme was integrated into the open source operating system Contiki. The aim of this thesis/project is to bring CTC to smartphones (Android), using the already existing Contiki implementation of our scheme. This will open a variety of new applications such as controlling ZigBee devices via smartphones.
