Multi-node data exchange traffic analysis for a communication framework embedded on smart meters

摘要

This paper proposes a multi-frame communication framework, which is open, scalable and supports multiple connection from smart meters. The framework uses an architectural model based on Design Patterns and Object Oriented principles to guarantee a high cohesion and low coupling among its modules. In this sense, the main contribution of the present paper is to analyze the behaviour of an innovative communication framework in a realistic data transfer scenario. For this purpose, the multi-connection performance was evaluated based on packet throughput and computational cost on the processing device that receives connections from other nodes. Moreover, it was also considered the computational cost due to data encryption and the use of distinct hardware devices to validate the interoperability and define the limitations and constraints. For these purposes, some laboratory experiments were performed, demonstrating that the proposed framework is able to avoid a burst of data transfer for simultaneous connections and to support a good overall throughput in the server node (between 1406.14 and 2120.27 KB/s). Thus, the proposed framework represents a reliable and maintainable solution that can be embedded in smart meters.
