Load balancing in Cellular Network: A review

Abstract

Mobile Stations (MSs), in real-world systems, are not evenly distributed across cells. Thus, MSs in a hot cell are affected by the load imbalance and might unable to get services. Load balancing became one of the most active and emerging fields of research in Cellular Network. In order to balance the load among different cells, it is needed to transfer the over-loaded traffic from hot cells to neighbouring cooler ones. Various dynamic load balancing schemes to deal with the unbalanced traffic problem are already proposed. In this paper we have reviewed various techniques of load balancing in cellular network. We have also presented two comparison tables for the reviewed schemes. This work would help look at a glance to the previous works done in the area of Load Balancing in Cellular Networks.
