1. Design of Wireless Embedded Thin Web Server Based on Zigbee
ZigBee wireless network is a kind of ad hoc networks, built on dynamic on-demand
routing protocols, and has such strong points like automatic routing repair, low consumption;
high reliability Embedded Web server is the device that the web server software is built into
hardware. It has the advantage that its control can be accessible from any web browser via the
Internet. Nowadays, embedded web server systems are becoming increasingly popular in the area
of remote control. Those systems are mostly formed by using Field bus technology based on
classical wired connections.
A new design of embedded web server making use of ZigBee, a wireless network
technology, is proposed in this paper .Compared to the wired link web server system, this system
is characterized by having no wires between the web server and terminal nodes ,lower cost ,and
having more flexibility of the network topology.
Existing system:
In the existing system we will use wired connections such as CAN, LIN to collect the
details about nodes. Even though offering a lot of convenience, our existing system has some
drawbacks as high cost, difficult maintenance, and more wired connections. So we will introduce
a new system which will have wireless connections between server and nodes. We will make this
system using ZigBee technology.
Proposed system:
We introduce a new a new design of embedded web server making use of ZigBee, a
wireless network technology in this paper. Compared to the wired link web server system,
This system is characterized by having no wires between the web server and terminal nodes,
lower cost, and having more flexibility of the network topology. For every node we will use
separate ZigBee transceiver to transmit the details to server node.
