Analysis of The Energy Efficiency of Wireless Communication When Receiving A Data Stream

Abstract

Abstract In this article, the tasks of energy efficient operation of a mobile station in wireless communication system were considered. At the same time, the main attention was paid to the consideration of ensuring energy efficient data delivery to the mobile station while meeting the transmission delay requirements. In particular, the operation of a standard power saving mode control algorithm in an IEEE 802.16m network was investigated. Issues related to the functioning of this algorithm when receiving data streams with variable intensity were studied. To conduct such a study, a model of a data transmission system was developed and a universal characteristic was introduced for comparing various control algorithms for the energy saving mode-the energy efficiency coefficient. In addition, an optimization problem was formulated for choosing the parameters of the energy saving mode. After analyzing the existing control algorithm for the energy saving mode, an effective control algorithm was proposed, the use of which makes it possible to achieve a gain in the energy efficiency coefficient of up to 20% when receiving a data stream with variable intensity.
