Poster Abstract: Towards Ambient Backscatter as an Anti-jamming Solution for IoT Devices

Reliable communication for Internet of Things is challenging when strong jamming signals are transmitted. The difficulty lies in the fact that in order to enable reliable communication, the system needs to create a communication channel beyond jamming signals. In this paper, we propose a first jamming resilient technique by switching the channel from Wi-Fi to ambient backscatter. Our vision is that ambient backscatter makes the transmitter to be jamming resilient through frequency shifting and modulation to existing signals. The proposed technique is effective than other anti-jamming solutions in that it reduces frame error rate more than 70% despite the existence of jamming signals.
