The foreseen explosion in online video traffic over the upcoming years has left current mobile operators struggling to maximize their networks capacity and efficiency. MEDIEVAL project aims to evolve existing architectures through relevant cross-layer interactions, permitting to deliver expected QoE levels to users. In order to alleviate the impact of(More)
—Legacy IEEE 802.11 does not efficiently support multicast transmissions. In order to cope with the increasing demand for multicast, mainly required to deliver multimedia traffic, the IEEE 802.11aa Task Group has recently standardized new mechanisms to allow efficient and robust transmission of multicast flows in Wireless LAN. However, the standard allows(More)
In this paper we present our vision on future uses of the Media Independence paradigm developed within the IEEE 802.21. We argue that this specification is an excellent starting point for future applications that require the handling of heterogeneous technologies. The current IEEE 802.21 standard facilitates media independent handovers by providing higher(More)
Optimized video delivery, Quality of Experience (QoE) and customer satisfaction are key issues to be addressed by mobile network operators while providing next generation video services to their users. The sharp increase in video traffic, the diversity of video applications and the availability of advanced smart-phones create new challenges that require a(More)
