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 is
robust in the coexistence environment of diverse wireless technologies since
the signal correlation works well in bad wireless channel conditions. It achieves
standard compliance and transparency without any hardware and firmware
changes. We have implemented CoSense on the Universal Software Radio Peripheral (USRP) platform to verify its feasibility. The experimental exploration reveals
that CoSense significantly reduces the false-positive and false-negative rate under
typical setting and the additional overhead is negligible. The results show that our
scheme saves much energy by up to 63% in dynamic network interference scenarios where low-power ZigBee transmissions are overwhelmed by strong Wi-Fi
signal interferences.},
