Frame-based adaptive video transmission over a cooperating femto-multilink environment

Nowadays the importance of multilink networks where end-to-end connections are provided by applying multiple communication networks simultaneously is rapidly growing. Besides that, femtocells are currently being investigated as a low-cost solution for enhancing the spectral efficiency and offload data from overstretched networks. The combination of multilink architecture and cognitive femtocells provides an effective coverage extension possibility and Quality of Service (QoS) improvement. In this paper this possibility is investigated for the case of uplink video transmission. The efficiency of an adaptive transmission scheme will be presented for a terrestrial heterogeneous multilink network that consists of WiMAX and UMTS networks and interworks with femtocells.
