Abstract

The cellular concept is a major breakthrough in solving the problem of spectral congestion. It increases system capacity by providing the possibility of frequency reuse. The demand for higher capacity and better service quality in wireless mobile communication systems has been increasing exponentially in the last decade. Code division multiple access CDMA cellular systems provide higher capacity, better quality of service QOS, and higher data transfer rates. CDMA systems offer many benefits that make them more bandwidth efficient than FDMA and TDMA systems. Signals from different mobile stations propagate through different radio channels and undergo different multipath effects before arriving at base station. A well-defined transmission power control is essential for proper functioning of CDMA systems. In the absence of power control, capacity of CDMA systems is very low. With a proper power control it is possible to prolong the mobile battery life. In this article we take the overview of power control techniques in CDMA cellular mobile communication systems.

Abstract

For many Internet applications, the ability to protect the identity of participants in distributed applications is critical. Traffic analysis of the Network can infer who is talking to whom over a public network. For such applications, a number of anonymous communication systems have been realized over the recent years. The effectiveness of these systems relies greatly on the way messages are routed among the participants. It is difficult to design a system that provides anonymity for delay-sensitive services such as Web browsing. Existing systems are either not resistant against sophisticated attacks or they achieve their level of anonymity at the cost of a high bandwidth overhead. Designing mix-networks for low-latency applications that offer acceptable performance and provide good resistance against attacks without introducing too much over-head is very difficult. In this paper, I analyzed the Onion routing network by implementing Onion Routing Node in Public environment and compared the performance of Onion routing network with other Anonymous Networks. Also for the different types of attacks on Anonymous network, the response of onion routing is discussed with some recommendations to make these attacks difficult.

Abstract

As IT departments and the communications industry move to a single converged voice and data network solution, the demand on the network to provide specific service levels increases. This demand for higher and differentiated service levels for certain applications has created a need for a reliable and scalable Quality of Service (QoS) model in the network. Prior to the introduction of Voice over IP (VoIP) into a production network, the environment must be equipped to support the reliable transport of voice and a solid end-to-end voice quality plan must be defined and in place.

Typical demands on the network when supporting voice are continuous uptime (99.999%) and consistently low deviations in latency (jitter). As a real-time application, VoIP is far more sensitive to latency, jitter, and packet loss than standard data applications as users have no tolerance for garbled or broken speech. VoIP continues to be compared to traditional telephony in terms of voice quality and reliability as this is the level of service quality to which most users are accustomed.

To support diverse transmission requirements of multi-media applications QOS should be provided in the internet, however the Internet is still working on best effort services. IETF has provided two models for providing QOS on the Internet i.e. IntServ, DiffServ. IntServ model is rarely deployed due to its heavy resource utilization as it reserves the resources end to end for providing QOS. However DiffServ model can be used to provide low latency, guaranteed service to critical network traffic such as voice and video while providing simple best effort traffic guarantees to non critical service such as web traffic. Our research work will mainly focus on testing the implementation of multi-media applications using signaling protocols like SIP, H.323, etc in IP networks. We will deploy test bed based on Internet routing architecture using protocols like BGP4 for Inter Domain Routing, OSPF for Intra Domain Routing and QOS based on DiffServ model.

Abstract

Control Objectives for Information and related Technology (COBIT) is an IT governance framework and supporting toolset that allows managers to bridge the gap between control requirements, technical issues and business risks. To aid organizations in successfully meeting today business challenges, the IT Governance Institute (ITGI) has published version 4.0 of COBIT.

COBIT enables clear policy development and good practice for IT control throughout organizations. IT Governance Institute latest version- COBIT 4.0-emphasizes regulatory compliance, helps organizations to increase the value attained from IT, enables alignment and simplifies implementation of the COBIT framework.

While the COBIT guidelines have been around since 1996, the guidelines and best practices have almost become the de facto standard for auditors and SOX compliance, mostly because the COBIT standards are platform independent. While using the framework provided, each company will need to customize the approach to its own size and complexity. A multinational, multidivisional organization is different from a single factory domestic company.

When reviewing and applying the COBIT guidelines and best practices, they need to be tailored to the particular environment.

The aim of this RD is to study the COBIT framework, its application in various domains and to come up with the best practices and guidelines for its application

Abstract

Regulation is often regarded as among the key challenges facing the banking industry today. Despite ongoing concerns about the bugbear of regulation and the subsequent costs imposed on the financial industry, it is universally acknowledged that regulation is essential in today world. Some drivers for regulations include the rise of global terror links, accounting scandals and other operational issues.

The Sarbanes Oxley Act of 2002, signed into law on july 30 2002 is one of the most significant changes ever legislated to US Federal Securities law. It was motivated by the never ending waves of corporate financial scandals. One of the most significant provisions within the SOX is the criminal and civil penalties that place executive management and the Board of Directors.

SOX require a new level of corporate governance and accountability.
