ABSTRACT

In the fundamental operation in computer science, Graph algorithm is a great tool used to solve problems related to graph theory and this algorithms have wide applications in solving routing problems. For the purpose of this project four algorithms from the many types of graph algorithms were selected which are Dijkstra’s, Bellman-Ford, kruskal and prim’s Algorithm and it application in solving network routing problem was discussed and tested using a hypothetical scenario where results showing the shortest path between data points in a typical communication network was calculated and display using JAVA programming language to implement it on Netbeans IDE 8.2. However, bellman-ford algorithm which is an algorithm that deals with negative edges does not produce the same output as the rest algorithms due to the data used in testing them all which was a limitation in the test.
