Receiver-Sensitivity Control for Energy-Efficient IoT Networks

To increase energy efficiency of receiver-dominated nodes in IoT networks, we introduce Receiver-Sensitivity Control (RSC). RSC enables a trade-off between communication range and reception efforts. This is achieved through multiple receiver-sensitivity levels that can be adjusted at run time. The receiver operate on lower sensitivity with reduced power consumption conserve if the received signal quality sufficiently high or otherwise use higher to avoid packet re-transmissions. We evaluate technique simulation realistic network scenario. results show substantial savings about 10-20% for better-than-worst-case channel conditions.
