Improving horizontal handover performance of real time applications over homogeneous wireless networks

Ambient networks are envisioned to be a combination of diverse but complementary access technologies. Internetworking these types of networks will provide mobile users with ubiquitous connectivity across a wide range of networking environments. The composition of existing and emerging heterogeneous wired/wireless networks requires the design of intelligent networks components to enable mobile users to switch network access and experience uninterrupted service continuity anywhere, anytime by keeping the same connection performance as before. We focus on WLAN performances analysis and optimization techniques this based on advanced network simulator, OPNET modeler. Many practical issues are considered with proposed solutions. Experimental results with Opnet Modeler under different scenarios are presented. The test-bed is first described, followed by the results and analysis. We concluded the paper with a summary of the key results of the work.
