Wang and compeers then send data packets to the known Google Maps ruins servers in this large area to find which routers they pass through. When a souvenir machine and the target micro* have shared a router, the researchers can compare how long a packet takes to reach each machine from the router; converted into an valuation of distance, this time dissimilarity narrows the search down further. 'We shrink the size of the area where the target potentially is,' explains Wang. Finally, they repeat the promontory search at this more fine-grained level: comparing delay times once more, they fix which feature server is closest to the target."
