| Abstract(in English) | In our previous research, we realize a Home Energy Management System (HEMS) as an ASP service with the Websocket protocol, which can provide Web-based bidirectional communication channels. We showed that the proposed architecture can reduce the server load and the network traffic significantly. However, the performance evaluation has been conducted by only simple mathematical analysis. In this report, we designed the cloud-based HEMS assuming energy control from HEMS server to Air conditioners and LED lightings in households, and evaluated its performance by implementation experiments. We found that the memory usages of the HEMS server increase in nearly proportion to the number of households. On the other hand, CPU utilization and end-to-end message delay fluctuate unpredictably according to the number of CPU cores. We concluded that the usage of multi-core processor largely affects the performance of HEMS server. |
