A Hybrid Resource Management Technique for Energy and QoS Optimization in Fractional Frequency Reuse Based Cellular Networks

This paper presents a new technique for jointly optimizing energy consumption and quality of service (QoS) in heterogeneous cellular networks employing fractional frequency reuse (FFR) in the macrocell tier. The proposed technique combines radio resource management (RRM) and network routing principles to produce an effective way of utilizing the spectrum. Based on a novel method of interference mapping, the RRM is invoked, in distributed or centralized manner, to allocate the resource. In the case of ...
