Load Balancing Optimization in LTE/LTE-A Cellular Networks: A Review.

摘要: During the past few decades wireless technology has seen a tremendous growth. The recent introduction of high-end mobile devices further increased subscriber's demand for high bandwidth. Current cellular systems require manual configuration and management networks, which is now costly, time consuming error prone due to exponentially increasing rate users nodes. This leads self organizing capabilities network with minimum human involvement. It expected permit higher end user Quality Service (QoS) along less operational maintenance cost telecom service providers. Self organized networks incorporate collection functions automatic configuration, optimization networks. As continue use resources while moving from cell boundary other, traffic load within does not remain constant. Thus Load balancing as part solution, become one most active emerging fields research in Cellular Network. involves transfer overloaded cells neighbouring free more balanced distribution order maintain appropriate end-user experience performance. In this paper, review various techniques currently used presented, special emphasis on that are suitable feature future
