A Mobility Framework for OMNeT++

Communication networks are an important application area for OMNeT++. While fixed topology networks are relatively easy to implement with the available means, an easy to use and effective extension for mobile networks is still missing. We present a framework for OMNeT++ to support simulations of mobile networks. The framework is intended to be deployable ’as is’, without the need to adapt existing modules, as well as to be easily extensible to fit the requirements of a particular problem. Especially, it should provide a unified structure, allowing switching between different levels of abstraction, without changing the communication logic on top of it. The framework has three main components. First it provides a set of independent modules that implement node mobility, dynamic connection management and a wireless channel model. Second, it includes a library of standard modules for common protocols. And third, it suggests design guidelines for simulation models of wireless devices, e.g., a blackboard for automatically exchanging information between various communication protocols.
