Abstract
WiMAX (worldwide interoperability Microwave access) IEEE 802.16 is an accepted standard for mobile networks and when we are discussing WiMAX mobility the most important factor involving the performance of WiMAX network is handover. There has been numerous papers published regarding handover. This work discusses the implementations of Dual-Triger Handover DTHO algorithm for WiMAX networks. This algorithm is based on SNR (Signal to Noise Ratio) computation which are received at Mobile stations. These measurements of SNR and free capacity for BS and MS improves the accuracy of reception level which in turn improves the handover decisions. The nodes such as BS and MS do not trigger handover and it is the mutual decision between nodes which decides and that is why it is implemented at both nodes. This work was simulated on OPNET Modeller version and the results have shown less delay in the handover process in WiMAX services.
