An energy-aware TCP for multimedia streaming
Mohamed Oulmahdi, Christophe Chassot, Ernesto Expósito · 2013
Multimedia streaming distributed applications, such as uTube or Deezer, imply transmission of important amount of audio and/or video data that induce non-negligible energy consumption. In the same time, those applications are generally characterized by a certain level of losses tolerance. With the aim to reduce the energy consumption associated with the distribution of such applications, this paper proposes an energy-aware mechanism for TCP-based Transport protocols (TCP, MPTCP for instance) that exploits the loss tolerance of multimedia applications by reducing the offered QoS to the minimum required. Simulations results demonstrating the benefits induced by the proposed architecture are carried out using the NS-3 simulator. The obtained results allow showing that the main benefits are induced by a global diminution of the overall transmission.
