An energy-saving scheme for cellular networks based on frequency distribution

We propose an energy saving scheme for wireless access networks called FDS (Frequency Distribution Scheme), which associates frequency allocation with service classes. In this scheme we construct a multi-period algorithm and a TSM (Traffic Supervision Mechanism) to adaptively distribute as few frequencies as possible while still satisfy the traffic demand. We implement our scheme in a sample wireless network, and the simulation results show that our scheme not only saves frequency resources, but also reduces the transmission power.
