Abstract: We propose a peer-to-peer (P2P) home monitoring system architecture to exploit a vacuum robot with an IP camera, a movable IP camera. The key implementation issues for the proposed system are: i) the easy configuration of a vacuum robot to connect to Wi-Fi network; ii) the session management between a vacuum robot and a home monitoring server; iii) the support of the network address translator (NAT) traversal between a vacuum robot and a user terminal. To solve these issues, we use and extend the Wi-Fi protected setup (WPS), the session initiation protocol (SIP), and the user datagram protocol (UDP) hole punching. To configure a vacuum robot easily, we present the GENERATE method which is an extension to the SIP that allows for the generation of a SIP URI. To reduce the load on the server for NAT traversal, we also devise the low time-to-live (TTL)-based UDP hole punching scheme.
