Τhe ever increasing demand for video data in mobile networks tends to generate a gap between what users are asking for and what wireless access providers can offer. On the one hand, wireless access providers respond to this demand by investing in advanced wireless technologies that will allow them to achieve Gbps speeds in wireless environments. However, such speeds are generally achieved at short distances, requiring a dense arrangement of wireless access points. Therefore, wireless access providers are required to make costly investments both in wireless technology research and in network infrastructure, while their flexibility in balancing these costs is rather limited due to fixed-price data plans. On the other hand, network users realize that the common 2-3 Gbyte monthly data plans do not suffice to download more than two movies from Netflix sites at normal quality. VELOS aligns with those who argue that a different approach is needed to disconnect the quality of users' experience and the amount of data they consume in their devices from the maximum data transmission rate in wireless links. Technically, the approach is based on innovative caching techniques at the edge of the wireless access network.

Τhe project is funded by the ΕU European Structural and Investment Funds - Partnership Agreement 2014-2020 framework, in the context of action "Support of researchers with emphasis on young researchers" of the Human Resources Development, Education and Lifelong Learning sectoral program.
