Expert system for open-loop power control of wireless local area networks
چکیده انگلیسی

This paper considers an embedded fuzzy expert system for non-feedback uplink power control of wireless local area networks (WLANs). The main idea is to minimize the transmission power of the nodes while keeping the transmission errors at an acceptable level. In the developed method, receivers collect signal strength values which are used by the control systems to define an acceptable transmission power level. The functionality of the proposed solution is demonstrated with simulations, which prove that the use of the expert system to open-loop systems can significantly decrease transmission power, increase energy efficiency and decrease interference to adjacent access points and associated nodes.


► Irregular bursts intervals prevent the delivery of the real-time feedback information.
► Received signal strength values are used for acceptable power level definition.
► Transmission power is minimized while bit errors are kept at an acceptable level.
► Controller decreases transmission power and interference increasing energy efficiency.
