Efficient Free-Rider Detection Using Symmetric Overlays

Edge-computing is one of the most promising techniques to leverage the excess capacity that exists at users´ premises. Unfortunately, it may be vulnerable to free-riding, i.e., To nodes that attempt to benefit from the infrastructure without providing any service in return. In this short paper we address free-riding in the context of edge-assisted streaming and propose the use of carefully crafted symmetric overlays to support message dissemination and efficient free-rider detection.
