This thesis describes a software framework for the development of communication protocols. The requirements for communication protocols and their overall complexity are constantly increasing. Development, testing and verification as well as the hardware implementation have become significantly more challenging over the years. Computer simulations are a common tool to support these processes in an efficient way. For the simulation of aspects of the physical protocol layer, point-to-point links are usually analyzed by simulation on bit-level. For higher protocol layers, so called network simulation tools are employed. The logical layer at the borderline between physical and all the higher layers is called data link layer. In many existing tools this layer is kept very abstract and it is largely neglected. The main contribution of this thesis is an enhancement of the existing network simulator ns–3. In combination they form a versatile software framework for the development of communication protocols. The complete physical layer aspects as well as channel aspects of the existing simulator are re-engineered. The goal is to have a structure that differentiates between aspects that can be influenced by communication devices, i.e. physical layer aspects, and aspects that cannot be influenced, i.e. the channel. In existing simulators, such as ns–3, this distinction does not always exist clearly, if at all. We introduce the point of view of a communications engineer in an environment that has mostly been built by computer scientists. The presented software framework enables the potential users to employ actual machine code within the simulator. Hence, program code intended for the actual hardware devices can be developed and tested using the network simulation framework. All protocol layers of the hardware protocol stack can be run, except the physical layer. This means that our enhancement also includes the possibility to run, develop and test the often neglected data link layer. Consequently, the efficiency of protocol ...
