Load Balancing for Centralized Wireless Networks

Abstract:
Recently, centralized wireless network architecture has been proposed for efficient system resource management and cost-effectiveness. Radio over fiber (or cable) networks and centralized wireless LAN systems are representative instances. However, this architecture requires us to reconsider system level control schemes since most of research efforts in this field has been focused on distributed network architecture. In this paper, we propose a load balancing scheme for centralized wireless networks using the capability that users in the overlapping area between cells can efficiently and dynamically be reconnected to one of the accessible base stations by a central control station. A simulation study is done to compare the proposed scheme with conventional load balancing ones, showing the proposed scheme is more efficient in system resource utilization.
