Abstract

This paper proposes a scheme for distributed load balancing in mobile communication networks based on a supervisory control framework. Using load information exchanged with neighbors, the “supervisors” that reside in the base stations distribute the load among cells by controlling handover parameters in a distributed manner. The supervisors are designed so that the load difference among neighboring cells are kept under a pre-defined threshold. Simulations show that our approach can effectively balance load among cells and thus reduce call blocking rate of the overloaded cells.
