Abstract—Scalable video transmission over a network is easily adaptable to different types of mobile experiencing different network conditions. However the transmission of differentiated video packets in an error-prone wireless environment remains problematic. We propose and analyze a cross-layer error control scheme that exploits priority-aware block interleaving (PBI) in the MAC layer for video broadcasting in CDMA2000 systems. The PBI scheme allocates a higher priority to protecting the data which are more critical to the decoding of a vid ....etc

Most of us know of TCP/IP as the glue that binds the Internet. But not as many can offer a cogent description of what it is and how it works. So what is TCP/IP, really? TCP/IP is a means for networked computers to communicate with each other. It doesn't matter whether they are part of the same network or are attached to separate networks. It doesn't matter if one computer is a Cray and the other a Macintosh. TCP/IP is a platform-independent standard that bridges the gap between dissimilar computers, operating systems, and networks. It's the pr ....etc

Digital scent technology



INTRODUCTION
Until now online communication involved only two of our senses, sense of hearing and sense of sight. Soon it will involve the third, the sense of smell. A new technology is being developed to appeal to our sense of smell. Bringing alive our experience, technology now targets on the sense of smell.

Using Electronic-nose we can sense a smell and with a technology called Digital scent technology it is possible to s ....etc

4G WIRELESS SYSTEM




ABSTRACT
Fourth generation wireless system is a packet switched wireless system with wide area coverage and high throughput. It is designed to be cost effective and to provide high spectral efficiency. The 4g wireless uses Orthogonal Frequency Division Multiplexing (OFDM), Ultra Wide Radio Band (UWB), and Millimeter wireless. Data rate of 20mbps is employed. Mobile speed will be up to 200km/ ....etc

BiCMOS simple explanation


INTRODUCTION

In integrated technologies, BiCMOS, also called BiMOS It is the integration of BJT and CMOS technology into a single device.

In the 1990s modern integrated circuit technologies began to make BICMOS a reality.

BICMOS Circuit uses the characteristics of each type of transistor most appropriately.

Generally this means that high current circuit use metal oxide semiconductor field effect transistor (MOSFETs) for effi ....etc

TCP/IP



Application layer

The function of this layer generally is to sand and receive the data. We will explain some applications.
1- DHCP → port no.67
This program assign dynamic IP's pc address to
The hosts instead of static IP's.
2- Web → port no.80
This program publishes the web sites. So that the
Web client programs like internet explorer can
Request the web sites from web servers.
3- DNS → port 53
Mapping from ho ....etc
