Initialization of Handover Procedure in WiMAX Networks
Source: Czech Technical University
This paper introduces a new approach in the triggering of handover procedure in WiMAX networks. Mobile WiMAX, based on the IEEE 802.16e standard, supports a several types of handovers and allows full mobility of users. The originating IEEE 802.16j standard introduces new network entities called relay stations. A relay station enables either throughput enhancement in the selected area or enlargement of a coverage area of base station. Both IEEE 802.16e and IEEE 802.16j standards utilize downlink channel parameters to set up the initialization of a handover procedure. To increase the overall network throughput, the proposed method initializes a handover procedure based on evaluation of maximal network throughput in uplink or downlink direction.
