In this paper, a novel design and implementation of a geographical observation system based on P2P agents is described. We propose sensor agent architecture to realize efficient and real-time notifications of sensor information. In this architecture, sensors act as agents and send updated notification messages to the observer agents which satisfy specified conditions by making use of multiple overlays. These features are implemented on P2P agent software 'PIAX'. In this implementation, Web browsers and cellular phones can act as observer agents.
