The research work is novel because previous studies have implemented the shortest path algorithms using Floodlight or POX controller, but this study uses a Python supported RYU controller and performs better compared to previous studies. The research work done in this article can be extended to ...
Back before computers were a thing, around 1956, Edsger Dijkstra came up with a way to find the shortest path within a graph whose edges were all non-negative values. To this day, almost 50 years later, his algorithm is still being used in things such as link-state routing. It has ...

Open Shortest Path First (OSPF) is a routing protocol for IP networks. It is used within a network or area. OSPF is an interior gateway protocol designed for a single autonomous system.OSPF uses a link-state routing algorithm. Each router has information about every link and router in the ...
Hello, can this algorithm be used for solving routing problems, eg finds a path between a start point and end-point? Comment byProuso01— February 3, 2012 @21:13 Nice, I’ll try to implement this. Is A* + JPS only efficient with 2D squared grids ?
On termination of a run, 𝐿(𝑣)L(v) will then store the length of the shortest s-v-path in the graph. If a vertex v has a label 𝐿(𝑣)=∞L(v)=∞, then no s-v-path is possible. In its most basic form, Dijkstra’s algorithm can be described in just three steps: ...
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–Warshall, cannot be extended to large-scale road ...
Their paper presented the earliest finish charging (EFC) algorithm to solve the charging path problem. They described the characteristics of electric vehicle charging behavior through three processes: from the origin to the charging station, while charging at the station, and from the charging station...
