A Comparative Study And Analysis Of Pvm And Mpi For Parallel And Distributed Systems, Dr. Syed Jamal Hussain, Ghufran Ahmed Aug 2005

A Comparative Study And Analysis Of Pvm And Mpi For Parallel And Distributed Systems, Dr. Syed Jamal Hussain, Ghufran Ahmed

International Conference on Information and Communication Technologies

Networks of Workstations (NOWs) based on various operating systems are globally accepted as the standard for computing environments in the IT industry. To harness the tremendous potential for computing capability represented by these NOWs, various new tools are being developed. Parallel Virtual Machine (PVM) and Message Passing Interface (MPI) have existed on UNIX workstations for some time, and are maturing in their capability for handling Distributed Parallel Processing (DPP). This research is aimed to explore each of these two vehicles for DPP, considering capability, ease of use, and availability, and compares their distinguishing features; and also explores programmer interface and …


Poster Session A: Address Auto-Configuration In Mobile Ad Hoc Networks Using Olsr, M.U. Saleem, Shoaib Mukhtar Aug 2005

Poster Session A: Address Auto-Configuration In Mobile Ad Hoc Networks Using Olsr, M.U. Saleem, Shoaib Mukhtar

International Conference on Information and Communication Technologies

Mobile Ad Hoc Networks is dynamic multi-hop network that is formed by a set of mobile wireless nodes that are sharing the same bandwidth. So every node possibly acts as a host as well as a router. In traditional networks, hosts can depend on the central servers like DHCP for IP assignment and management, but it cannot be extended to MANET due to its distributed and dynamic nature. Many solutions have been proposed, amongst them some are try to extend the stateless configuration of IPv6 for MANET; others distribute IP addresses among nodes (using binary distribution). Most of these proposed …


Poster Session A: Analyzing & Enhancing Energy Efficient Communication Protocol For Wireless Micro-Sensor Networks, Irfan Majeed Butt, Shoab Ahmed Khan Aug 2005

Poster Session A: Analyzing & Enhancing Energy Efficient Communication Protocol For Wireless Micro-Sensor Networks, Irfan Majeed Butt, Shoab Ahmed Khan

International Conference on Information and Communication Technologies

The paper presents an analysis of energy efficient routing protocols with direct communication protocol. A comparison of these protocols is made analyzing energy consumption at each node and explaining system lifetime after certain rounds. The paper also proposes a novel energy conscious cluster head selection algorithm for making system more reliable and efficient. Simulation shows that our proposed algorithm enhances the system reliability and accuracy.


Poster Session A: Use Of Neural Networks In Multi-Sensor Fusion For Remote Sensing Applications, Engr. S. M. Haider Aejaz Aug 2005

Poster Session A: Use Of Neural Networks In Multi-Sensor Fusion For Remote Sensing Applications, Engr. S. M. Haider Aejaz

International Conference on Information and Communication Technologies

Remote sensing encounters different types of objects with similar spectral signatures. Multi-sensors form the solution of the problem with spectral different parts of the spectrum and the resulting information is then processed using digital signal processing techniques. Artificial neural networks provide another method for processing this information. The research describes how neural networks may be used to classify objects on the basis of their spectral response to different frequencies.


Poster Session A: A Multi-Priority Application Framework For Mobile Ad Hoc Networks, M. Ibrahim Channa, Ahsan Chaudhry, Kashif Sharif, Irum Memon Aug 2005

Poster Session A: A Multi-Priority Application Framework For Mobile Ad Hoc Networks, M. Ibrahim Channa, Ahsan Chaudhry, Kashif Sharif, Irum Memon

International Conference on Information and Communication Technologies

The fast spread of small wireless computers has enabled the design and deployment of wireless Ad Hoc networks. Typical applications proposed for such networks include both Real Time and Non-Real Time applications. We propose an architecture that provides a complete framework for Real Time applications and Best Effort traffic. The proposed architecture comprises of an Ad Hoc Routing Protocol for route setup and route repair, a Bandwidth Allocation and Reservation Scheme for Real Time traffic, and a MAC layer protocol that provides traffic differentiation. The Admission Control module is used to admit or reject a new Real Time flow request …


Keynote: Emerging Era Of Cooperative Empowerment: Grid, Peer-To-Peer, And Community Computing, Dr. Javed I. Khan Aug 2005

Keynote: Emerging Era Of Cooperative Empowerment: Grid, Peer-To-Peer, And Community Computing, Dr. Javed I. Khan

International Conference on Information and Communication Technologies

In this paper we discuss an emerging trend in high performance computing-the social or community computing. The emergence of screensaver computing, grid computing, peer-to-peer systems, and their demonstrated ability to garner computing power as potent as the supercomputers seems to be auspicious. In this paper we discuss the new phenomenon of community computing-including their potential applications in solving a new set of grand challenge problems. We also discuss the previously uncharted technological challenges architects of these new paradigms are addressing.


Tcp Attack Analysis On Packets Captured Using Symantec Decoy Server, Ali Bakhtiar Nizamani, Bahari Belaton Aug 2005

Tcp Attack Analysis On Packets Captured Using Symantec Decoy Server, Ali Bakhtiar Nizamani, Bahari Belaton

International Conference on Information and Communication Technologies

This paper discusses results obtained from Symantec Decoy Server (previously known as Mantrap) with an introduction to honeypots. Lance Spitzner of the Honeynet Project introduced the concept of honeypots. A honeypot is in essence a decoy server, which has no real or strategic value and is only setup to attract crackers towards it. The idea is to trap the crackers and learn cracking techniques from them. Rapid increase in unauthorized intrusions over the Internet provides a great motivation to explore honeypots at a greater depth. We will provide analysis on TCP based denial of service attack carried out on Symantec …

Exploring The Possibility Of Implementing Telecommuting At University Utara Malaysia (Uum), Dr. Wan Rozaini Sheik Osman, Haitham Rashdan Aug 2005

Exploring The Possibility Of Implementing Telecommuting At University Utara Malaysia (Uum), Dr. Wan Rozaini Sheik Osman, Haitham Rashdan

International Conference on Information and Communication Technologies

Global technology has quickly progressed to provide more accessible business modes of communication. The image of the traditional workplace as a particular place to go to work is being replaced with employees working wherever they can be most efficient and productive, whether at home, on a plane, on the road, or a telework center. The availability of affordable technology has been one of the major contributors to the "any time, any place" telecommuting trend. The purpose of this study is to investigate the possibility of the implementation of teleworking at University Utara Malaysia (UUM), the suitable job selection criteria, the …


G-Value Decoding Of Greedy Codes, Khalil Ahmad Aug 2005

G-Value Decoding Of Greedy Codes, Khalil Ahmad

International Conference on Information and Communication Technologies

Error-correcting codes are widely used to increase the reliability of transmission of information over various forms of communication channels. Codes with a given minimum distance d can be constructed by a greedy algorithm [2]. In this paper, I proposed a new algorithm for the allocation of g-values to the binary vectors. Hamming (7, 4, 3) code can be generated by the application of greedy algorithm on the binary vectors of length 7 arranged in B-ordering. This code is used to demonstrate a new decoding technique for linear codes in addition to the schemes already known for decoding such as Syndrome …
