The paper "Augmenting Home Routers for Socially-Aware Traffic Management" by Andri Lareida, George Petropoulos, Valentin Burger, Michael Seufert, Sergios Soursos, Burkhard Stiller was accepted for publication at the 40th Annual IEEE Conference on Local Computer Networks (LCN) from October 26-29, 2015 in Clearwater Beach, FL, USA.

Mobile users' Quality-of-Experience (QoE) is degrading as network usage increases while Internet Service Providers (ISP) face increased inter-domain traffic. This paper presents a network traffic management mechanism, named RB-HORST, addressing these inefficiencies. RB-HORST exploits home routers by using them as caches and forming an overlay network between them to transfer content. To shift traffic from peak hours, RB-HORST employs predictions based on social network properties and based on similarity in the overlay network. To further improve user QoE, home routers allow trusted mobile devices to offload their mobile connection to the local WiFi. Simulation results show that an overlay is imperative for the success of the proposed caching mechanism. Especially ISPs with a large number of customers can benefit if only every thousandth user shares its router, reducing inter-domain traffic by half and superseding an ISP operated cache. The presented implementation proves that the concept is technically feasible and can be deployed and run on constrained devices.
