Hi Robin, Sorry it's taken a while for someone to respond to your email. Many of us have been on leave from the start of December until this week.

Since I would like this project to bring a real contribution to the Tor development, I want to make sure that all the steps I will perform are useful and/or worth it. > > The master thesis plan: https://drive.google.com/open?id=1XEOSS29owavKJ_cJJAVaPiJe34Ez6XXx > The poster: https://drive.google.com/open?id=1BlF2U-Kexyz6ihVSqvsVHv4PUsvXATc4 Have you considered relay bandwidth capacity, measured bandwidth, consensus weight, or bandwidth authorities in your plan? When using the Tor path selection algorithm, relay consensus weight has a big impact on the paths selected by clients. At the moment, relay consensus weight is a function of relay bandwidth capacity, and geographic location. For a map of consensus weights, see "Consensus Weight versus Bandwidth" on: https://atlas.torproject.org/#map Have you considered relay operators or relay families? In particular, operators that could perform end-to-end correlation? https://nusenu.github.io/OrNetStats/ Have you considered the relay's Operating System? Are you aware that the Tor network has historically been a Linux monoculture, and 90% of relays still run Linux? https://nusenu.github.io/OrNetStats/ https://torbsd.github.io/blog.html Have you considered the Tor version that the relay is running? https://nusenu.github.io/OrNetStats/ Recently, someone created a website that gave badges for different kinds of relay diversity. But I can't remember what it was called. I've also cc'd nusenu, who has done some work in this area.
