A novel load balancing scheme for QoS provisionings over heterogeneous wireless networks

Load balance is a key technology in future heterogeneous wireless networks due to its merits like improving resource utilization, enlarging system capacity and providing QoS for users. This paper presents a load balancing scheme which is composed of QoS-based and load-related admission control and dynamic vertical handover. The scheme can provide better QoS and jointly optimize resource utilization. Simulation results show that the proposed scheme can provide better performance in packet loss rate and load balance than the traditional scheme which a user is admitted to the network with the least connections.
