Wireless Sensor Network With Centralized Embedded Web Server
Using ARM7
Abstract:
A plat form independent embedded web server and its
integration into a network of wireless sensor nodes is implemented here. The
embedded web server is designed and built as an expansion module for one of the
nodes in the Wireless Sensor Network (WSN). It allows authorized Internet users
to establish two-way communication with the sensor network. The server uses
limited available hardware resources to implement an interface to the WSN node.
This allows the user to monitor the operation of the WSN remotely, to
periodically download the sensed data and to change the operation mode of the
network. In this project, by typing the IP-address of LAN on the web browser,
the user gets a web page on screen; this page contains all the information
about the status of the devices. The user can also control the devices
interfaced to the web server by pressing a button provided in the web page.
