Novel transmission mechanisms are imperatively needed to cope with the exponential growth of mobile traffic and its associated power consumption. To address such challenges, we present lookahead video delivery schemes that jointly improve the streaming experience and reduce BS power consumption. This is accomplished by exploiting knowledge of future wireless rates users are anticipated to face. Such...
In this paper we consider packetized video transmission in cooperative relay-based wireless networks. We propose algorithms for optimized relay selection that take into account the content of each specific video packet. Our first algorithm, that is designed for a narrowband flat-fading channel and single-carrier modulation, selects jointly the optimal relay and video packet for forwarding. Our next...
The explosion of demanding on-line services, such as video, is increasingly stressing the Internet architecture, requiring new solutions to support future usage scenarios. New Future Internet approaches targeting Information Centric Networking, such as the Entity Title Architecture (ETArch), provide new optimizations for these scenarios, using novel mechanisms such as Software Defined Networking (SDN)...
Allocation of wireless spectrum and transmission power for video multicast in a two-tier femtocell network is a challenging problem because of network dynamics, variable video bit-rates, and heterogeneous clients who watch various videos as well as are at different locations. Since femtocells provide coverage using typical cellular system air interface, the co-channel interference may significantly...
