An energy efficient power control mechanism for base stations in mobile communication systems

The development of ICT (Information and Communication Technology) industry has emerged as one of the major sources of world energy consumption Especially, energy consumption on base station is a large portion of total energy consumption In this paper we study with energy efficient power control mechanism for base station in mobile communication systems. We proposed a efficient sector power control based on distance between base station and mobile node. Also we proposed a sleep mode energy control mechanism In sleep mode energy saving protocol, each sector monitors the number of user in sector cell. If number of mobile node falls down a given threshold in sector cell, base station shuts down power. Simulation demonstrate the Tx energy of proposed algorithms and the tradeoff between energy saving and cell coverage.
