Abstract

The aim of this project is to develop a Virtual Routing Network Emulation Framework for testing Routing protocols and algorithms. The core of this framework will be virtual routers running in user space and the component realising their virtual interconnection. This framework will be based around a network topology emulation notion.
This report contains details on the motivation, design and implementation behind the provision of a Virtual Routing Framework.

Introduction to cdma2000 Standards for Spread
Spectrum Systems


OVERVIEW

The cdma2000 Family of Standards
The cdma2000 family of standards includes core air interface, minimum performance, and
service standards (see 1.3). The cdma2000 air interface standards specify a spread
spectrum radio interface that uses Code Division Multiple Access (CDMA) technology to
meet the requirements for Third Generation (3G) wireless communication systems. The
core air interface standards in the family are [ ....etc

3G CDMA - WCDMA and cdma2000
Rules for Efficient Multiple Access
Three laws
 Know the channel
 Minimize interference to others
 Mitigate interference received from others
 Requirements of wireless multiple access
 Channel measurement
 Channel control and modification
 Multiple user channel isolation
Why CDMA?
 Higher capacity
 Improved performance in multipath by diversity
 Lower mobile transmit power = longer battery life
 ....etc

Computer Aided Teaching System

The Computer aided teaching system is a frame work to create Interactive Multimedia Tutorial CD's. Using this software the user can create tutorials with Images, Movies, Audio clips, Descriptions etc. The inbuilt speech SDK will read the descriptions in the tutorial for the end user. The aim of this project is to help the teachers with basic computer knowledge to create interactive tutorials for their students.

The project will have a single administrative module. The administrator can follow the tutorial cr ....etc

ABSTRACT
 UHF TV channels are traditionally used for television broadcasting where the channels can be regarded static or slowly-varying.
 In this paper, new results on the temporal and spatial characteristics of the wideband UHF mo-bile wireless signals and channels in the Digital Television (DTV) broadcasting UHF frequency bands are presented.
 Our analysis of DTV mobile field measurements confirms that the com ....etc

CDMA2000 is a technology for the development of cdmaOne/IS-95 to 3rd generation services. Also known as IMT-CDMA Multi-Carrier or IS-2000 is the main route for CDMA operators to second-and-a-half ( 2.5G) and third generation (3G) cellular networks. A set of new standards that define the new air interface and the Radio Access and Core Network changes that will enhance network capacity, improve speed and bandwidth to mobile terminals, and allow end-to-end IP services has been created by the standard-setting body behind CDMA2000 known as 3GPP2.

ABSTRACT

RFB (Remote Frame Buffer) protocol enables remote users to share the desktop of the server either exclusively or on a sharing basis.

RFB (remote frame buffer) is a simple protocol for remote access to graphical user
interfaces. Because it works at the frame buffer level it is applicable to all windowing
systems and applications, including X11, Windows 3.1/95/NT and Macintosh.
The remote endpoint where the user sits (i.e. the display plus keyboard and/or pointer) is
called the VNC client. The endpoint where changes to the fram ....etc

Abstract—In this paper, the problem of efficient distributed power control via convex pricing of users' transmission power in the uplink of CDMA wireless networks supporting multiple services is addressed. Each user is associated with a nested utility function, which appropriately represents his degree of satisfaction in relation to the expected trade-off between his QoS-aware actual uplink throughput performance and the corresponding power consumption. Initially, a Multiservice Uplink Power Control game (MSUPC) is formulated, where each user ....etc
