Inter-Cell Interference Reduction Via Store Carry and Forward Relaying

The integration of mobile relays in cellular networks has been recently envisioned as a way of increasing system capacity, coverage and reducing communication energy consumption. The authors studied how Store Carry and Forward (SCF) relaying within the cell can be utilized as an underlay message forwarding mechanism to achieve system wide energy savings. In this paper, by deriving optimal routing policies to reduce either the total energy consumption or the total transmit power, they show that the SCF relaying scheme reduces considerably inter-cell interference.
