Abstract
This paper considers non-feedback uplink power control for wireless local area networks. In the proposed solution, the main idea is to minimize transmission power of the nodes, while keeping the transmission errors at an acceptable level. The purpose is to save energy and decrease unnecessary interference. In the developed method, receivers collect received signal strength values from which the embedded fuzzy expert system defines acceptable transmission power level. The functionality of the proposed solution is demonstrated via simulations, which prove that with fuzzy system it is possible to significantly decrease transmission power and increase the energy efficiency of the access networks as well as to decrease interference to adjacent access points and associated nodes.
