A first sequence is formed by sorting the set of landmark devices relative to the network-communication delays between the target device and each landmark device. For each respective landmark device, an additional sequence is formed by sorting other landmark devices relative to the network-communication delays between the respective landmark device and the other landmark devices. A sequence-matching operation is applied to the first sequence and the additional sequences to form a ranking of the set of landmark devices relative to the target device.
