PIAX (P2P Interactive Agent eXtensions) is an open source framework that integrates P2P structured overlay network and agent platform. PIAX is implemented by Java. PIAX can be used as a messaging platform for data gathering from the sensor network, parallel/distributed data analysis and delivering the analysis results to the actuators for facility controllers and visualization devices like digital signage. An overview of PIAX is shown in Figure 8. PIAX has its own testbed operated by NICT. It can be used to test PIAX Agent implementation easily.
