Security evaluation of data exchange path in infrastructure networks

This paper presents a method to and the best path for data exchange in communication systems of infrastructure networks. This method is based on Floyd-Warshall shortest path algorithm and is implemented in MATLAB. In this paper, we considered a typical example of a communication system over a power network modeled as a graph. In this graph, control centers, some power plants, some important substations and some interface communication centers role as nodes. The branches of the graph are weighted according to communication characteristics of links. Also in this example the best path for data exchange is derived. Then the weighted graph is optimized and the algorithm is used again. Comparing the paths before and after the optimization and their weights show the level of optimization.
