通过仿真和真实世界的实验来分析通信协议需要在这两个领域中仔细地实现协议。实现的差异可能导致性能结果的显著差异，这可能对协议设计过程产生不利影响。提出了一种用于无线接入研究平台（WARP）设备的代码透明仿真与实验框架——WARPsim。通过适当地扩展模拟引擎，可以将运行在WARP设备上的相同应用程序代码用于模拟。本工作通过在WARP设备上实现时间关键的介质访问控制层（MAC）协议的示例研究了这种方法的含义。在演示中，将使用WARPsim模拟各种MAC协议，同时更改协议参数，以及仿真硬件的关键方面。集成到框架中的图形表示允许对协议行为进行直观的检查。
Analyzing a communication protocol by means of simulation and real-world experimentation requires careful protocol implementation in both domains. Differences in the implementation may lead to significantly diverging performance results, which may affect the protocol design process adversely. A code-transparent simulation and experimentation framework for Wireless Access Research Platform (WARP) devices is proposed, which is called WARPsim. By extending the simulation engine appropriately, the same application code that runs on WARP devices can be used for simulation. This work studies the implications of this approach using the example of implementing time-critical Medium Access Control Layer (MAC) protocols on WARP devices. In the demonstration, various MAC protocols will be simulated using WARPsim, while changing protocol parameters, but also crucial aspects of the emulated hardware. A graphical representation integrated into the framework allows for an intuitive examination of the protocol behavior.
