Scanning on handover enhancement issues in video application deployments on WiMAX mobile networks

WiMAX evolution is expected to go through Wireless broadband last mile access, backhaul solutions ending with handset integration. This paper outlines the challenging scenario WiMAX networks face when deploying mobile Internet applications, including the most demanding in terms of latency and data rate: the video applications. The proposed strategy to enhance global network performance has been to apply new handover policies. Several validation methodologies have been approached: testbeds, simulation scenario and a mixed real-to- simulation scenario.
