This paper investigates an architecture for interconnecting Internet and Zigbee sensor network which is founded on IEEE802.15.4 standard. We present a web-sensor gateway to deliver data between Internet protocol and Zigbee/IEEE802.15.4 protocol, transparently. We also introduce the common gateway interface (CGI) technology to satisfy users on the web browser to efficiently manage and query the Zigbee sensor network, ubiquitously. Finally, a simulation prototype is proposed. Keywords-Web-sensor gateway; Zigbee sensor network; Zigbee/IEEE802.15.4 protocol; CGII.
