# aqua-sim-fg
We will soon update the full version of aqua-sim-fg, including more network protocols and a more realistic underwater acoustic propagation model. In addition, aqua-sim-fg will also support hybrid programming with MATLAB and Python.

# Python  hybrid programming
1. Install cppyy
```
python3 -m pip install --user cppyy==2.4.2
```
2. Building ns-3    
```
./ns3 configure --enable-python-bindings
./ns3 build
```
3. Add  ns3 lib and ns-python to your path
```
export PATH=$PATH:/your_ns_path/ns-3.38/build/lib
export PYTHONPATH=$PYTHONPATH:/your_ns_path/ns-3.38/build/bindings/python
export LD_LIBRARY_PATH=/your_ns_path/ns-3.38/build/lib
```
4. Running
```
python aloha.py(An example in examples)
```
note: you can also use the precompiled python library (bindings and lib folder)

# MATLAB hybrid programming

1. Install MATLAB and MATLAB Compiler
1. Install MATLAB runtime
1. Compile a custom MATLAB function `xxx()` to a C++ library using `mcc -W cpplib:libxxx -T link:lib xxx`
1. Move `libxxx.h` to `NS3PATH/src/aqua-sim-fg/model/include` and Move `libxxx.so` to `NS3PATH/src/aqua-sim-fg/model/lib`
1. Append MATLAB-related header and library files paths to `NS3PATH/CMakeLists.txt` as follow:
```cmake
include_directories(MATLAB_RUNTIME_PATH/R2023a/extern/include)
link_directories(MATLAB_RUNTIME_PATH/R2023a/runtime/glnxa64)
link_directories(${CMAKE_SOURCE_DIR}/src/aqua-sim-fg/model/lib)
link_libraries(mwmclmcrrt)
link_libraries(xxx)
```
You may need to append the MATLAB Runtime library to LD_LIBRARY_PATH if it's not an Ubuntu 22 system.
6. Enable MATLAB using `asHelper.SetMatlab(true)`

7. An example is as follows:

# Mobility model and channel model
1. Bellhop model is used to enable more accurate channel simulation. The communication environment can be configured via the `env` file in the `config` folder.
2. Multiple underwater vehicle mobility models are implemented. The AUV's movement trajectory can be configured via `config/command.config`.
