摘要：
This paper considers wireless sensor networks (WSNs) and quantitatively rates energy efficiency obtained by combining adaptive power/rate control with adaptive modulation scheduling. For multi-access wireless sensor networks, adaptive modulation and power control are two important means to increase spectral efficiency. An adaptive modulation with power control scheme (AM with PC) which mainly reduces power consumption to achieve energy efficiency for wireless sensor networks is proposed in this paper. Cluster head node of each link adaptively adjusts its power control level and modulation type according to the signal to noise ratio (SNR) and target bit error rate (BER). The efficiency of this approach is further illustrated via numerical comparison with the original AM with PC. Simulation results demonstrate that the proposed scheme, which alleviates to save much transmission power and maintains the target bit error rate, can significantly improve the system performance.
