Reducing power consumption of mobile access networks with cooperation
Matthias Herlich, Holger Karl · 2011
The base stations of modern mobile access networks do not only provide high data rates but also consume large and barely varying amounts of power. When the load on the network is low it consumes much more power than necessary. We answer the question of how much power can be conserved in mobile access networks when some base stations use cooperative transmissions to extend their range while others are deactivated. In addition, we analyze the effect of different path-loss exponents and varying number of cooperating base stations.
