Landmark path algorithm

WebbDuring a pre-processing phase, which requires two shortest path computations per landmark using Dijkstra’s algorithm, all distances to and from these landmark nodes are computed and stored. Afterwards the heuristic estimates the distance from a vertex to another vertex using the already computed distances to and from the landmarks and … Webb5 jan. 2024 · IPv6 geolocation is necessary for many location-based Internet services. However, the accuracy of the current IPv6 geolocation methods including machine-learning-based or deep-learning-based location algorithms are unsatisfactory for users.
