The shortest path algorithm performance comparison in graph and relational database on a transportation network

open access: yesPromet (Zagreb), 2014
In the field of geoinformation and transportation science, the shortest path is calculated on graph data mostly found in road and transportation networks. This data is often stored in various database systems.

Shortest Path Finding in Quantum Networks With Quasi-Linear Complexity

open access: yesIEEE Access, 2023
A fully-quantum network implies the creation of quantum entanglement between a given source node and some other destination node, with a number of quantum repeaters in between.

Upgrading Shortest Paths in Networks [PDF]

open access: yes, 2011
We introduce the Upgrading Shortest Paths Problem, a new combinatorial problem for improving network connectivity with a wide range of applications from multicast communication to wildlife habitat conservation. We define the problem in terms of a network with node delays and a set of node upgrade actions, each associated with a cost and an upgraded ...

Shortest path discovery of complex networks [PDF]

open access: yesPhysical Review E, 2009
In this paper we present an analytic study of sampled networks in the case of some important shortest-path sampling models. We present analytic formulas for the probability of edge discovery in the case of an evolving and a static network model. We also show that the number of discovered edges in a finite network scales much slower than predicted by ...

CASPaR: Congestion avoidance shortest path routing for delay tolerant networks

open access: yesInternational Journal of Distributed Sensor Networks, 2017
Unlike traditional transmission control protocol/Internet protocol–based networks, delay/disruption tolerant networks may experience connectivity disruptions and guarantee no end-to-end connectivity between source and destination.

Maritime Transport Network in Korea: Spatial-Temporal Density and Path Planning

open access: yesJournal of Marine Science and Engineering, 2023
The increase in maritime traffic and vessel size has strengthened the need for economical and safe maritime transportation networks. Currently, ship path planning is based on past experience and shortest route usage. However, the increasing complexity of

Ndist2vec: Node with Landmark and New Distance to Vector Method for Predicting Shortest Path Distance along Road Networks

open access: yesISPRS International Journal of Geo-Information, 2022
The ability to quickly calculate or query the shortest path distance between nodes on a road network is essential for many real-world applications. However, the traditional graph traversal shortest path algorithm methods, such as Dijkstra and Floyd ...

Shortest paths and centrality in uncertain networks

open access: yesProceedings of the VLDB Endowment, 2021
Computing the shortest path between a pair of nodes is a fundamental graph primitive, which has critical applications in vehicle routing, finding functional pathways in biological networks, survivable network design, among many others. In this work, we study shortest-path queries over uncertain networks, i.e., graphs where every edge is ...

Shortest-Path Routing in Arbitrary Networks

open access: yesJournal of Algorithms, 1999
Summary: We introduce an on-line protocol which routes any set of \(N\) packets along shortest paths with congestion \(C\) and dilation \(D\) through an arbitrary network in \(O(C+D+\log N)\) steps, with high probability. This time bound is optimal up to the additive \(\log N\), and it has previously only been reached for bounded-degree leveled ...
