Load Balancing Early Handoff Scheme for Multimedia Data Transmission in Wireless Networks

This study developed a load balancing early handoff scheme that enables transfer part of heavy load in a base station to the others using the overlap between base stations in wireless cellular networks. The proposed scheme reduces the new call blocking probability (CBP) and handoff call connection dropping probability (CDP) as well as to increase the resource utilization of wireless networks. Since the scheme is triggered by a connection request received by the base station, it immediately reflects the loading of the base station. The proposed load balancing early handoff policy can be integrated in diverse call admission control schemes. The effectiveness of the load balancing early handoff scheme is demonstrated by integrating it with DMTBR to improve the call admission control function. Additionally, NS2 is used to simulate the load balancing early handoff scheme in a wireless network with wrap-around model. The simulation results show that the proposed scheme can effectively improve the wireless network resource utilization.
