Abstract
The satisfaction level of femtocell users depends on the availability of requested bandwidth. But, the xDSL line that can be used for the backhauling of femtocell traffic cannot always provide sufficient bandwidth due to the inequality between the xDSL capacity and demanded bandwidth of home applications, like IPTV, PC, Wi-Fi, and others. A Service Level Agreement (SLA) between xDSL and the femtocell operator (mobile operator) to reserve some bandwidth for the upcoming femtocell calls can increase the satisfaction level for femtocell users. In this paper, we propose a SLA negotiation procedure for femtocell networks. The Bandwidth Broker controls the allocated bandwidth for femtocell users. Then, we propose the dynamically reserved bandwidth scheme to increase the femtocell user's satisfaction level. Finally, we present our simulation results to validate the proposed scheme.
