INTRODUCTION
When we talk about optical communication, most people think about optical-fiber. But optical communication is also possible without optical-fiber. We know that light travels through air for a lot less money. This makes possible the optical communication without optical-fiber. Optical communication without fiber is known as Free Space Optics. It is used due to economic advantages. Since the introduction of internet the backbone traffic is increasing at the rate greater than 100%, hence the owner of the backbone ....etc

Abstract— This is the model for displaying notices in colleges on electronic notice board by sending messages in form of SMS through mobile; it is a wireless transmission system which has very less errors and maintenance. The hardware board contains microcontroller AT89c52 at the heart of the system. The microcontroller is interfaced with GSM Modem via MAX232 level convertor. It is used to convert RS232 voltage levels to TTL voltage levels and vice versa. The hardware also has a 64K EEPROM chip AT24C64. This EEPROM ....etc

Asymmetrical Digital Subscriber Line

1.Links subscriber and internet service provider only for residential users.

2.Uses existing local loops.

3.Uses currently installed twisted pair cable.

4.Can carry broader spectrum of 1MHz or more.

ADSL CONFIGURATION

The twisted pair local loop is actually capable of handling bandwidths up to 1.1Mhz, but the filter installed at the end office of the telephone company where each local loop terminates limits the bandwidth to 4Khz(for voice comm.). If the filter is removed the entire 1.1Mhz i ....etc

This paper presents two efficient flooding algorithms based on 1-hop neighbor information. In the first part of the paper, we consider sender-based flooding algorithms, specifically the algorithm proposed by Liu et al. In their paper, Liu et al. propose a sender-based flooding algorithm that can achieve local optimality by selecting the minimum number of forwarding nodes in the lowest computational time complexity O(n logn), where n is the number of neighbors. We show that this optimality only holds for a subclass of sender-based algorithms. We ....etc
