Designing efficient yet flexible medium access controllers (MAC) for wireless protocols is a challenge. Not only are these protocols still evolving, they are also increasingly demanding in terms of throughput and real-time requirements. In order to support a careful application-driven architecture development, reference applications are required that expose the full system and enable the quantitative evaluation of performance-flexibility tradeoffs. For this purpose, we have captured the 802.11n MAC protocol in an executable reference application which comprises the system function and its environment including traffic scenarios. We model the reference in Click, a packet processing framework. The functionally-correct model captures performance-relevant aspects such as the wireless protocol timing exactly. Leveraging extensions to Click we can use the model for the development and deployment of embedded architectures. Our 802.11n MAC model comprises between 118 and 1238 functional elements and can be simulated in real time depending on the scenario. Due to ts modularity, additional scenarios can be added productively.
