Drawing One-Hop Links Using the Common Open Research Emulator (CORE) Service

Abstract: The current version of Common Open Research Emulator (CORE) used in the Network Science Research Laboratory only considers the distance-based formula to draw links on the graphical user interface (GUI) to represent network connectivity. This model works by calculating the pixel distance between two nodes positioned on the GUI surface then comparing the transposed pixel distance into meters whereby it can be compared to the maximum allowable distance between nodes. If the calculated distance is less than or equal to the maximum distance value, the link is drawn. This report describes a process for adding a service to CORE that will gather one-hop neighbor information based upon Open Shortest Path First (OSPF) and Optimal Link State Routing (OLSR) protocols. The network connectivity can then be displayed on the CORE GUI as well as other visualization tools used within the Network Science Research Laboratory based upon methods other than the distance-based formula.
