WiMAX Handover Conditions Evaluation towards Enhancement through Cross-Layer Interaction

In the context of micro and macro-mobility capabilities defined by IEEE 802.16e/WiMAX standards, the paper presents the simulation campaign undertaken to identify the sets of configuration parameters having a major impact on the handover process for the IEEE 802.16e mobile station. Simulation results could then be used to construct a database for guiding some cross-layer optimization algorithms deciding upon handover trigger, in order to increase the handover performance, from the application point of view.
