Networks - I: Pre-Coordination Mechanism For Self Configuration Of Neighborhood Cells In Mobile Wi-Max, Abdul Qadeer, Khalid Khan Dec 2011

Networks - I: Pre-Coordination Mechanism For Self Configuration Of Neighborhood Cells In Mobile Wi-Max, Abdul Qadeer, Khalid Khan

International Conference on Information and Communication Technologies

WiMax broadband services successfully providing triple play (Voice, Video and Data) support with combating the challenges of better quality and interoperability. Support for smooth mobility in real time with no wired infrastructure and being surrounded by GSM waves demanding a comprehensive and powerful network. Covering large areas through number of base stations which not only require time to configure but also need resources for implementation with a recurring cost of functionality. Automation is everywhere and to provide novel wireless services it is necessary to come up with some distinct features like intelligent base stations which have the capability of doing …


Wireless Networks: Spert: A Stateless Protocol For Energy-Sensitive Real-Time Routing For Wireless Sensor Network, Sohail Jabbar, Abid Ali Minhas, Raja Adeel Akhtar Aug 2009

Wireless Networks: Spert: A Stateless Protocol For Energy-Sensitive Real-Time Routing For Wireless Sensor Network, Sohail Jabbar, Abid Ali Minhas, Raja Adeel Akhtar

International Conference on Information and Communication Technologies

Putting constraints on performance of a system in the temporal domain, some times turns right into wrong and update into outdate. These are the scenarios where apposite value of time inveterate in the reality. But such timing precision not only requires tightly scheduled performance constraints but also requires optimal design and operation of all system components. Any malfunctioning at any relevant aspect may causes a serious disaster and even loss of human lives. Managing and interacting with such real-time system becomes much intricate when the resources are limited as in wireless sensor nodes. A wireless sensor node is typically comprises …


Networks - Ii: Overhead Analysis Of Security Implementation Using Ipsec, Muhammad Awais Azam, Zaka -Ul- Mustafa, Usman Tahir, S. M. Ahsan, Muhammad Adnan Naseem, Imran Rashid, Muhammad Adeel Aug 2009

Networks - Ii: Overhead Analysis Of Security Implementation Using Ipsec, Muhammad Awais Azam, Zaka -Ul- Mustafa, Usman Tahir, S. M. Ahsan, Muhammad Adnan Naseem, Imran Rashid, Muhammad Adeel

International Conference on Information and Communication Technologies

Authentication, access control, encryption and auditing make up the essential elements of network security. Researchers have dedicated a large amount of efforts to implement security features that fully incorporate the use of all these elements. Currently, data networks mainly provide authentication and confidentiality services. Confidentiality alone is not able to protect the system, thus, suitable security measures must be taken. However, this security is itself an overhead which must be accounted for. A trade-off must exist between performance and security. This trade-off must be carefully managed so as not to deteriorate the systems being secured. This calls for the true …


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: 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: 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.

I have four important considerations for adoption of secured network model as secured network model for management information system.


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 …
