1. INTRODUCTION

In recent years, there has been a rapid increase in wireless network deployment and mobile device market penetration. With vigorous research that promises higher data rates, future wireless networks will likely become an integral part of the global communication infrastructure. Ultimately, wireless users will demand the same reliable service as today's wire-line telecommuni¬cations and data networks. However, there are some unique problems in cellular networks that challenge their service reliability. In addition to p ....etc

Science and technology with all its miraculous advancements has fascinated human life to a great extent that imagining a world without these innovations is hardly possible. While technology is on the raising slope, we should also note the increasing immoral activities. With a technical view, Power Theft is a non-ignorable crime that is highly prevalent, and at the same time it directly affects the economy of a nation. Data collected over Tirunelveli District, Bhel Trichy proves the ....etc

INTRODUCTION

Reliable user authentication is becoming an increasingly important task in the Web-enabled world. The consequences of an insecure authentication system in a corporate or enterprise environment can be catastrophic, and may include loss of confidential information, denial of service, and compromised data integrity. The value of reliable user authentication is not limited to just computer or network access. Many other applications in everyday life also require user authentication, such as banking, e- commerce, ....etc

ABSTRACT
The manual method of
synchronization demands a skilled operator and the method is suitable
for no load operation or normal frequency condition. under emergency
condition such as lowering of frequency or synchronizing of large
machines a very fast action is needed, which may not be possible for a
human operator. Thus there is a need of autosynchroniser in a power
station or in an industrial establishment where generator are employed.
This paper describes a m ....etc

INTRODUCTION
Efficient control of D.C motor speed is very economical to any industries for that reason we are using full wave rectifier in which we are using triacs as switches because of bi-directional nature of triacs we are preferred instead of using thyrister as a switches. To obtain a four quadrant operation we need 8 switches if we use thyristers (this circuit called dual converter) and if we use triacs we need 4 switches only.

ABSTRACT
In cellular networks, QoS degradation or forced termination may occur when there are insufficient resources to accommodate handoff requests. One solution is to predict the trajectory of mobile terminals so as to perform resource reservations in advance. With the vision that future mobile devices are likely to be equipped with reasonably accurate positioning capability, we investigate how this new feature may be used for mobility predictions. We propose a mobility prediction technique that incorporat ....etc

FINGER PRINT BASED ACCESS CONTROL SYSTEM
ABSTRACT:
According ancient Greek scripts BIOMETRICS means study of life. Biometrics studies commonly include fingerprint, face, iris, voice, signature, and hand geometry recognition and verification. Many other modalities are in various stages of development and assessment. Among these available biometric traits Finger Print proves to be one of the best traits providing good mismatch ratio and also reliable. The present scenario to operate a bank locker is with locks which are hav ....etc

Content Based Multicast Model In Ad Hoc Network

Abstract :

In this model, the content of the multicast data determines the receiver set for the data and the receiver set changes dynamically as the content of the multicast changes. Delivering the multicast to intended receivers while minimizing the message overhead and reducing battery consumption is a challenge made harder because of node mobility. This novel multicast model that distributes this form of threat information in a message efficient manner. In this report, result from detai ....etc
