Preface
A large class of routing protocols for MANETs, namely, reactive protocols, employs some form of caching to reduce the no. of route discoveries .the simplest form of caching is based on associating a timeout with each cache entry.
Such timer based cache scheme can increase the protocol efficiency. However the timeout is not well tuned, a sever performance degradation arises as entries are removed either too early or too late from the cache .
In this paper, we address the problem designing a proactive protoc ....etc

Definition
In the recent years communication technology and services have advanced. Mobility has become very important, as people want to communicate anytime from and to anywhere. In the areas where there is little or no infrastructure is available or the existing wireless infrastructure is expensive and inconvenient to use, Mobile Ad hoc Networks, called MANETs, are becoming useful. They are going to become integral part of next generation mobile services.

Pulse Based Dead Time Compensator for PWM Voltage Inverters



I. Introduction
The state of the art in motor control provides an adjustable
voltage and frequency to the terminals of the motor
through a pulse width modulated (PWM) voltage source inverter
drive. As the power devices change switching states,
a dead time exists. Although the dead time is short, it
causes deviations from the desired fundamental output voltage.
While each deviation does not appreciably affect the
fundamental voltage, the ac ....etc

A mobile ad hoc network (MANET) is a type of wireless ad hoc network, and is a self-configuring network of mobile devices connected by any number of wireless links. Every device in a MANET is also a router because it is required to forward traffic unrelated to its own use. Each MANET device is free to move independently, in any arbitrary direction, and thus each device will potentially change its links to other devices on a regular basis. The primary challenge for building a MANET is for each device to continuously maintain the information req ....etc
