In this paper, a structured methodology is proposed to define the architecture for a communication framework with multiframe capability, which can be embedded in a residential smart meter hardware for smart grid applications. This framework is based on the Transmission Control Protocol/Internet protocol, and it is considered that the data are exchanged via wireless technologies. The architectural model was based upon the state-of-the-art in software engineering, making use of the design patterns and the principles of low coupling and high cohesion, which result in a solution that is both more reliable and maintainable. A security module is also provided and the framework performance is evaluated, in terms of packet throughput and computational effort of the security layer on the processing device, via practical experiments of some laboratory scenarios. Furthermore, errors on some frames are introduced in order to evaluate the feasibility of this framework in real field applications. Results show that this framework architecture supports acceptable transfer rates even with extra computational cost due to the use of data encryption and separated processing modules, making it a feasible proposal for the considered application context.

智能电表的开源框架：数据通信和安全流量分析

在本文中，提出了一种结构化方法来定义具有多帧功能的通信框架的体系结构，该框架可以嵌入到智能电网应用的住宅智能仪表硬件中。该框架基于传输控制协议/互联网协议，认为数据是通过无线技术进行交换的。架构模型基于软件工程的最新技术，利用设计模式和低耦合高内聚的原则，产生了更可靠和可维护的解决方案。还提供了安全模块，并根据处理设备上安全层的数据包吞吐量和计算工作量评估了框架性能，通过一些实验室场景的实际实验。此外，引入了一些框架上的错误，以评估该框架在实际应用中的可行性。结果表明，即使由于使用数据加密和分离处理模块而产生额外的计算成本，该框架架构也支持可接受的传输速率，使其成为所考虑的应用程序上下文的可行建议。
