Joint Channel Allocation and Sampling Rate Control in EH-CRSNs,rk utility is an important indicator to evaluate data collection efficiency. Since network utility depends on the sampling rates of sensor nodes and network capacity, it motivates us to jointly study the sampling rate control and dynamic channel access to optimize the network utility in CRSNs.

Dynamic and Energy-Efficient Channel Access in Clustered CRSNs,grades. However, since the energy consumption for supporting the CR functionalities, e.g., channel sensing and switching, is critical for battery-powered sensor nodes [., .], the opportunistic channel access should be carefully studied to improve the energy efficiency in CRSNs.
