Abstract [en]

Due to their popularity, large coverage areas, and diversity of radio technologies, Low Power Wide Area Networks( LPWAN) will experience high levels of cross-technology interfer-ence. In this work, we  investigate the impact of LoRa interferenceon IEEE 802.15.4 (Wi-SUN) networks. Using hardware experiments, we characterize the interaction between these two verydifferent radio technologies. In particular, we observe that the IEEE 802.15.4 Clear Channel Assessment (CCA) mechanism does not  reliably detect interfering LoRa transmissions. We therefore propose an enhanced CCA mechanism based on a Multi-Layer Perceptron classifier and show that it significantly reduces the number of unsuccessful transmissions, while remaining compatible with the IEEE 802.15.4 standard.

Abstract [en]

We present a hardware platform for performing experimental studies of energy storage devices for low power wireless networks. It is based on a low-cost custom card that can apply fine-grain synthetic loads ? both charge and discharge ? to a set of batteries or capacitors and measure their response in detail. Loads can be defined from a "live" trace of a running wireless device, from a recorded trace, or programmatically via a script. This approach makes it practical to run well controlled, large scale, long running experiments and to obtain high precision and accuracy. We describe two proof-of-concept experiments using rechargeable Li coin cells and capacitors to demonstrate the capabilities of our platform.

Abstract [en]

The large number and wide diversity of IoT networks operating in unlicensed spectrum will create a complex and challenging interference environment. To avoid a 'tragedy of the commons', networks may need to more explicitly coordinate their use of the shared channel.

Abstract [en]

Advances in low power wireless communication have resulted in new radio technologies that can achieve long distance communication in energy efficient ways. An emerging problem in this scenario is interference between networks that share the same medium. The fact that these networks have a long transmission range increases the possibility of interference even more. Thus the investigation of how different networks can share the medium independently in a optimal way becomes an essential requirement for the IoT vision. In this poster, we present the first step of this investigation, which is measuring how LoRa and IEEE 802.15.4g PHY layers interfere.
