Wireless sensor networks consisting of hundreds to thousands of nodes are expected to find increasing deployment in coming years, as they enable reliable monitoring and analysis of physical worlds. These networks have unique features that are very different from traditional networks, e.g., the large number of nodes, limitation in power. Due to these unique features of wireless sensor networks, their management including querying becomes a challenging problem. In general, it is widely accepted that Web-based management should be used for managing and querying sensor networks. In this paper, we present the architecture of the sensor gateway for Web-based management and its implementation details. We assume that wireless sensor networks have 3-level regional hierarchy, but our gateway is flexible enough to cooperate with other type sensor networks. In addition, to make our gateway process user's query dynamically without intervention of user, a back socket is opened using Java applet. For this purpose, Java script code is embedded in Web page to link Java applet code.
