libgdtp is a generic data transfer protocol implementation that may be used to build packet-based communication systems for various purposes. It has been successfully employed for building fixed as well as dynamic spectrum access systems. It can be used standalone or paired with a software-defined radio framework or protocol simulator. libgdtp supports multiple flows with possibly different communication requirements, e.g., different levels of reliablity and priorities. libgdtp relies on Protocol Buffers for data serialization.

• Reliable and unreliable transfer service
• Simple stop and wait ARQ
• Multi-flow support
• Scheduler (FIFO, priority-based)
• Wrapper components for Iris and GNU Radio

1. Install some basic packet dependencies onto your system. E.g., using Ubuntu, invoke the following:

$ sudo apt-get install build-essential libboost-all-dev git cmake libprotobuf-dev protobuf-compiler protobuf-c-compiler liblog4cxx10-dev

2. Clone the repo to your machine:

    ```bash
$ git clone https://github.com/andrepuschmann/libgdtp.git libgdtp

3. Create a build directory and build.

$ mkdir build $ cd build $ cmake .. $ make $ make test $ make install

   
   Note: Building libgdtp for debugging goes like this ..

    ```bash
$ cmake -DCMAKE_BUILD_TYPE=Debug ..
