Abstract :
In this paper we present a controller for transmission power and packet length adaption to wireless channel attenuation change with an energy-efficiency goal. Due to convexity of energy function the controller can be based on Hill Climbing method. The proposed method achieves minimum energy point even in 12 steps, reducing complexity up to 10000 times compared to classical numerical evaluation, making it run-time compatible.
