Abstract Cross-technology interference (CTI) from diverse wireless networks
such as ZigBee, Bluetooth, and Wi-Fi has become a severe problem in the
2.4 GHz Industrial Scientific and Medical (ISM) band. Especially, low power
and lossy networks are vulnerable to the signal interferences from other aggressive wireless networks when they perform low power operations to conserve
the energy consumption. This paper presents CoSense, which accurately detects
ZigBee signals with a reliable signal correlation scheme in the presence of the
CTI. The key concept of CoSense is to reduce false wake-ups of low power listening (LPL) by identifying the pre-defined ZigBee signatures. Our scheme… More >
