ROOT-Sim Topology Library

Overview

The ROOT-Sim Topology Library provides a collection of common topological structures designed for simulation models. It is a companion library for the ROOT-Sim framework, facilitating the setup and management of simulated physical or logical communication networks among Logical Processes (LPs).

Features

This library supports mapping, adjacency management, and random neighbor selection for a variety of geometries:

• Linear/Ring Structures: Rings and Bidirectional Rings.
• Grid Structures: Square meshes, Hexagonal meshes, and Tori.
• Centralized Structures: Star topologies.
• Fully Connected: Fully Connected Meshes (FCMESH).
• Arbitrary Graphs: Custom Graph topologies with probability-weighted edges and custom data.

Integration

To use the topology library in your simulation models, include the main header:

#include <ROOT-Sim/topology.h>

This is a CMake-based C11 project. To build and link the library, ensure you have a C11-compliant compiler (like Clang or GCC) and CMake 3.12 or newer.

mkdir build
cd build
cmake ..
make
