Energy efficiency and self-organizing network architectures are the top issues for future cellular systems. In this paper, we propose an energy saving self-organizing access network architecture for long term evolution (LTE) cellular systems. Self-organizing nature is attained through intelligent cooperation among the evolved node Bs (eNBs) communicating via X2 interface in the LTE evolved UMTS terrestrial access network (E-UTRAN). Using the proposed coordination and cooperation, the E-UTRAN is dynamically reconfigured in real-time utilizing minimum number of active eNBs and switching the redundant eNBs into sleep mode. System performance under different network scenarios, cell layouts and eNB power consumption profiles is evaluated. Simulation results indicate a substantial drop in the network's energy consumption. In addition, the network becomes more efficient in utilization of its available capacity
