ZIGBEE CHATTING

AIM:

The aim of the project is to build the simple chatting application without Internet.

DESCRIPTION:

Increasingly communications-based

technologies such as Instant Messaging and chat

systems, are being used to enhance traditional

learning environments with tools that allow

students to formulate and exchange ideas. In this

paper we present Simple-Messenger, the first

Instant messaging system specifically designed

for beginners. Simple-Messenger has been

designed to assist in the teaching of how the

basic communication takes place.

By providing this example of an assistive

technology we hope to demonstrate how

innovative learning technologies can be tailored

to address issues relating to the educational

needs of Beginners and those who wish to

communicate with them.

This Proto-type project is developed by

using Zigbee module in succeeding for

transmitting and receiving data from one end to another end. This project can also used for chatting

purpose from one place/ system to another system without any internet. So that we can understand

how innovative project is this. In this project the data can be transmitted from one place to another

place and also the data will be very much secured when compared to the other very large networks

like internet. On this basis we also can develop Intranet.

ZigBee: is a low-cost, low-power, wireless mesh network standard. ZigBee chip vendors typically sell integrated radios and microcontrollers with between 60 KB and 256 KB flash memory. ZigBee operates in the industrial, scientific and medical (ISM) radio bands, and 2.4 GHz in most jurisdictions worldwide. Data transmission rates vary from 20 to 250 kilobits/second. The ZigBee network layer natively supports networks, and generic mesh networks. ZigBee is a specification for a suite of high level communication protocols using small, low-power digital radios based on an IEEE 802 standard for personal area networks.
