Load-Balancing QOS-Guaranteed Handover in the IEEE 802.11 Network

In this paper we propose the load-balancing QoS-guaranteed handover algorithm in the IEEE 802.11 network. We present our system load model in the IEEE 802.11 network and describe the optimal and fast handover algorithms. We evaluate our fast handover algorithm using system level simulation of the IEEE 802.11b network. Our fast load-balancing handover algorithm eliminates the overloading, thus guarantees meeting the QoS requirements of the users. It also provides a considerable throughput gain over the SNR-based handover algorithm
