This repository contains a simulation of the Optimized Link State Routing (OLSR) protocol using C++ and a custom simulation framework. The simulation models a network of nodes in an ad-hoc wireless environment, demonstrating the OLSR protocol's functionality.
To run the simulation, first ensure you have CMake and MSVC installed. Then, follow these steps:
git submodule update --init --recursive
mkdir build && cd build
cmake .. -G "Visual Studio 17 2022" -A x64
cmake --build .
./Debug/olsr-sim.exeInput network details as a txt file which can be chosen from the GUI. The format of the file is as follows:
# Number of nodes
# Adjacency matrix (0 for no link, 1 for link)
example:
4
1 1 1 0
1 1 0 1
1 0 1 1
0 1 1 1
Environment class manages the simulation environment, including node creation, movement, and communication. The Node class represents individual nodes in the network, handling message passing and routing logic.
The nodes are spun up in different threads to simulate concurrent operations. The simulation runs for a predefined duration, during which nodes exchange messages and update their routing tables.
