A Cost Function for Heterogeneous Networks Performance Evaluation
نویسندگان
چکیده
Heterogeneous cellular networks may be defined by several parameters that determine their performance, being known as the Key Performance Indicators (KPIs).. In order to guarantee a desired Quality of Service (QoS) a proper balance of these parameters is required. An approach to integrate a set of KPIs into a single one, is presented by using a Cost Function (CF). The CF takes these KPIs into account, providing a single evaluation parameter as output, and reflecting network conditions and Common Radio Resource Management (CRRM) strategies performance. The proposed CF model enables the implementation of different CRRM policies, by manipulating the KPIs, allowing for a better QoS.
