摘要: The Mobile WiMAX standard (IEEE 802.16e-2005) brings wireless broadband to a new level due the support of nomadism. Still, handover latency in is an issue that may affect real-time continuity application sessions. This partially Layer 2 scanning/ranging, as well network re-entry procedure, which result hundreds milliseconds, far exceeding requirement typical services (e.g., 150 ms for Voice over IP). In this paper, we describe mechanism incorporates information from several OSI Layers speed up handover. We show by means simulations can decrease significantly, less than 100 most cases.
