The typical future-tech scenario calls for millions of low-powered radio frequency devices scattered throughout our environment -- from factory-floor sensor arrays to medical implants to smart devices for battlefields.



Because of the short and unpredictable lifespans of chemical batteries, however, regular replacements would be required to keep these devices humming. Fuel cells and solar cells require little maintenance, but the former are too expensive for such modest, low-power applications, and the latter need plenty of sun.

ABSTRACT
The H.323 standard provides a foundation for audio, video, and data communications across IP-based networks, including the Internet. By complying to H.323, multimedia products and applications from multiple vendors can interoperate, allowing users to communicate without concern for compatibility. H.323 is an umbrella recommendation from the International Telecommunications Union (ITU) that sets standards for multimedia communications over Local Area Networks (LANs) that do not provide a guaranteed Quality ....etc

PART A
Simulation Exercises
Aim: To observe the effect of congestion by setting the parameters like, varying the queue size and page link bandwidth.
1. Simulate a three-node point-to-point network with a duplex page link between them. Set the queue size and vary the bandwidth and find the number of packets dropped.
Topology:-
Commands Used at Sender node and Receiver Node:
Sender:-
stcp –p 2000 –l 1024 1.0.1.2
Receiver:-
rtcp –p 2000 –l 1024
Results:
Case 1: set bandwidth to 10 Mbps and Queue size as 50

1). Introduction:
This document explains about VoIP systems. Recent happenings like Internet diffusion at low cost, new integration of dedicated voice compression processors have changed common user requirements allowing VoIP standards to diffuse. This how to tries to define some basic lines of VoIP architecture.
What is VoIP?
VoIP stands for ' Vâ„¢oice Ëœoâ„¢ver ËœIâ„¢nternet ËœPâ„¢rotocol. As the term says VoIP tries to let go voice (mainly human) through IP packets and, in d ....etc

POWER MANAGEMENT SYSTEM IN BPCL - KR

ABSTRACT
For the protection of power system, relays are used. Different types of relays include electromechanical, static and numeric relays. In an automated system numerical relay has a vital role. The project based on substation automation has been named as Power Management System.
Supervisory control and data acquisition (SCADA) allows a utility operator to monitor and control processes that are distributed among various remote sites. SCADA systems include hardware and software c ....etc

ABSTRACT
Managing packets in distributed multimedia environment involves coordinating and synchronizing multiple datastreams. The Ensembles Coordination Program provides the required coordination, reduces delay using path selection and message rebroadcasting, and allows the end application to manage the synchronization within the streams.
One immediate advantage of this mechanism (ECP) is the reduction of data rebroadcasts, because nodes with more than one adjacent nodes must send the data and only to those adjacent nod ....etc

Definition
Using an ordinary phone for most people is a common daily occurrence as is listening to your favorite CD containing the digitally recorded music. It is only a small extension to these technologies in having your voice transmitted in data packets. The transmission of voice in the phone network was done originally using an analog signal but this has been replaced in much of the world by digital networks. Although many of our phones are still analog, the network that carries that voice has become digital.

In todays phone networks, t ....etc

The limitations of the circuit-switching techniques of conventional telephony may now be overcome through integration with IP technologies. Internet Telephony is a powerful and economical communication option by combination of the telephone networks and data networks. IP telephony used to send audio, video, fax etc between two or more users in real time via packet switched network. The main motivation of IP telephony is Cost savings and ease of developing and integrating new services. Four type of IP telephon ....etc

RADIOISOTOPE THERMOELECTRIC GENERATOR(RTG)

INTRODUCTION

Radioisotope Thermoelectric Generator is a electrical generator.
It uses a radioactive material as the fuel and uses the fact that radioactive materials generate heat as they decay into nonradioactive materials.
This released heat is converted in to electricity by using Seebeck effect using an array of thermocouples.
The output obtained in a RTG is a steady output voltage and its power capacity is a few 100 W.
RTG provi ....etc
