Computer performance has been driven largely by decreasing the size of the chips while increasing the number of transistors they contain. In accordance with Moore?s law, this has caused chip speed to rise and prices to drop. However transistors can?t shrink forever. As components grow thinner, chip manufactures have struggled to cap power usage and heat generation. Even performances enhancing approaching like running multiple instructions per thread have bottomed out. In response manufactures are building chips with multiple cooler running, mor ....etc

Differentiated Bandwidth Allocation with TCP Protection in Core Routers


Abstract

Differentiated Services (DiffServ) networks categorize routers into edge routers and core routers.In core routers, one of the technological challenges is how to implement differentiated bandwidth allocation and TCP protection together with low complexity.We present an Active Queue Management (AQM) scheme called CHOKeW. A method is borrowed from a previous scheme, CHOKe, which draws a packet at random from the buffer, compares it with the arriving packet, a ....etc

Multi-core Supported Network and System Security and Security in Next Generation Wireless Networks
Abstract:-
This project have the implementation of a distributed agent architecture for intrusion detection and response in networked computers. Unlike conventional intrusion detection systems (IDS), this security system attempts to emulate mechanisms of the natural immune system using Java-based mobile software agents. These security agents monitor multiple levels (packet, process, system, and user) of networked c ....etc

Abstract
Two major factors that limit the throughput inmulti-hop wireless networks are the unreliability of wirelesstransmissions and co-channel interference. One promising techniquethat combats lossy wireless transmissions is opportunisticrouting (OR). OR involves multiple forwarding candidates torelay packets by taking advantage of the broadcast nature andspacial diversity of the wireless medium. Furthermore, recentadvances in multi-radio multi-channel transmission technologyallows more concurrent transmissions in the network, and sh ....etc

Design of complex Multi-Core Systems

Design of complex Multi-Core Systems

Bangalore. October 20-22, 2010

The advent of multi-core processors has changed the way computing is being offered to users. There has been a fundamental difference in the way systems need to be architected and designed, so as to make use of the new generation of processors. System designers have to suddenly grapple with various complex new issues, so that optimum use can be made of these new high-performance computing block ....etc

Transformer Basics
An electrical device that transfers energy from one circuit to another purely by magnetic inductive coupling.

Review of transformer losses
No load Loss (Excitation Loss) includes the hysteresis loss and eddy current loss.
excitation loss: energy lost by reversing the magnetic field in the core by the alternating AC.
mechanical loss: bearing friction,brush friction and windage loss

Load Loss (Impedance Loss)
Stray loss: It includes distortion of air-gap flux and also due to the due to non uniform ....etc

Seeing the technical difficulties in cranking higher clock speed out of the present single core processors, dual core architecture has started to establish itself as the answer to the development of future processors. With the release of AMD dual core opteron and Intel Pentium Extreme edition 840, the month of April 2005 officially marks the beginning of dual core endeavors for both companies.

The transition from a single core to dual core architecture was triggered by a couple of factors. According to Moore's Law, the number o ....etc

Abstract
With the increase of usage of wireless networks for purposes where the nodes are either stationary or minimally mobile, focus is also on increasing the network capacity of wireless networks. One such way is to use non-overlapping multiple channels provided by 802.11 by using multiple interfaces per node. Multiple nonoverlapped channels exist in the 2.4GHz and 5GHz spectrum. However, most IEEE 802.11-based multihop ad hoc networks today use only a single channel. As a result, these networks rarely can fully exploit the aggrega ....etc
