Load Balancing through Dynamic Partitioning for Hierarchical Cellular Networks

A novel autonomic area reconfiguration mechanism is proposed that complements hierarchical QoSR protocols in wireless access networks. The proposed mechanism revises the border between adjacent areas based on handover rates and on resource consumption in terms of bandwidth and user population. Its objectives are concentrated on reducing the overhead related with frequent inter-area handovers as well as providing bandwidth and user balancing on per area basis. This paper focuses on the load balancing aspects, exploring the contribution and effects of mobility through a simulation study.
