Adaptive Link Assignment Applied in Case of Video Streaming in a Multilink Environment

Nowadays the importance of multilink networks where end-to-end connections are provided by applying multiple communication links simultaneously is rapidly growing due to the expanding demand for high-speed Internet access and real-time video transmission. Since channel conditions may vary in time and space, the selection of the used communication links depends on traffic load, latency, coverage and desired data rate. Combining multilink architecture and adaptive video transmission can be therefore an effective solution for broadcasting video streams. In this paper the efficiency of the adaptive transmission scheme will be presented for a terrestrial heterogeneous multilink network which consists of WiMAX, LTE and HSDPA communication links.
