WLC17-4: Load-Balancing QoS-Guaranteed Handover in the IEEE 802.16e OFDMA Network

In this paper we propose a load-balancing QoS- guaranteed handover algorithm in the IEEE 802.16e OFDMA network. We describe our system load model for the IEEE 802.16e OFDMA network and propose the optimal and fast handover algorithms. We evaluate our fast handover algorithm using system level simulation of the IEEE 802.16e OFDMA network. Our fast load-balancing handover algorithm eliminates overloading, thus guarantees meeting the QoS requirements of the users. It also provides a considerable throughput gain over the traditional SINR-based handover algorithm.
