Effective Load Distribution Algorithm Considering Power and Interference Mitigation In A Dense Femtocell Based Network

This paper focuses on effective load distribution in a dense femtocell network. For densely deployed femtocell network, interference and power consumption are of big concern. There may be situations such as while covering a single UE (User Equipment), a femtocell interferes its neighbor cells badly. In such cases, if the UE is handed over to the neighbor cell with higher load, it is still capable of covering the UE. Then the interference can be mitigated leaving one cell empty. As femtocells are self configurable, an empty cell can change its state to standby mode; thus reducing the power consumption as well as interference. We have proposed an algorithm based on the load of a cell as well as its neighbor cells and SINR (Signal to Interference and Noise Ratio) of a UE for the cells. The proposed algorithm will assign a UE optimally choosing a FAP (Femtocell Access Point) or femtocell based on the load and SINR values.
