Dynamic Session Key Exchange Method using Two S-Boxes
Sohail Abid,Shahid Abid
Computer Science , 2012,
Abstract: This paper presents modifications of the Diffie-Hellman (DH) key exchange method. The presented modifications provide better security than other key exchange methods. We are going to present a dynamic security that simultaneously realizes all the three functions with a high efficiency and then give a security analysis. It also presents secure and dynamic key exchange method. Signature, encryption and key exchange are some of the most important and foundational Crypto-graphical tools. In most cases, they are all needed to provide different secure functions. On the other hand, there are also some proposals on the efficient combination of key exchange. In this paper, we present a dynamic, reliable and secure method for the exchange of session key. Moreover, the proposed modification method could achieve better performance efficiency.
Improving Performance of Routing Protocols Using MRP Framework
Sohail Abid,Shahab Khan
Computer Science , 2014,
Abstract: These days MANET is an amazing remarkably altering or rising technology, for the reason that of its elite nature of scattered mobile devices and self motivated network topology. The mobile adhoc routing protocol follows several principles in wireless MANETs. The up to date and novel applications based on wireless technology are being produced in the private as well as commercial sectors. A lot of challenges which are facing wireless MANETs like network stability, security, energy efficiency and performance analysis etc. At present wireless adhoc network get much more attention because of its accessibility everywhere. As a result researchers produce several routing protocols. In this paper first of all we analyzed the performance investigation of wireless routing protocols on the basis of ROH, throughput, end to end delay and PDR. After that we proposed an Mixed Routing Protocol framework which improve performance.
Energy efficient routing in mobile ad-hoc networks for Healthcare Environments
Sohail Abid,Imran Shafi,Shahid Abid
International Journal of Computer Science Issues , 2013,
Abstract: The modern and innovative medical applications based on wireless network are being developed in the commercial sectors as well as in research. The emerging wireless networks are rapidly becoming a fundamental part of medical solutions due to increasing accessibility for healthcare professionals/patients reducing healthcare costs. Discovering the routes among hosts that are energy efficient without compromise on smooth communication is desirable. This work investigates energy efficiency of some selected proactive and reactive routing protocols in wireless network for healthcare environments. After simulation and analysis we found that DSR is best energy efficient routing protocol among DSR, DSDV and AODV, because DSR has maximum remaining energy.

Improving energy efficiency in MANET's for healthcare environments

Computer Science , 2014,
Abstract: Now a day ad hoc mobile networks (MANETs) have lots of routing protocols, but no one can meet maximum performance. Some are good in a small network; some are suitable in large networks, and some give better performance in location or global networks. Today modern and innovative applications for health care environments based on a wireless network are being developed in the commercial sectors. The emerging wireless networks are rapidly becoming a fundamental part of every single field of life. Our proposed DEERP framework gives a better performance as compared to other routing protocol.
Green and Sustainable Heterogeneous Organo-Catalyst for Asymmetric Aldol Reactions  [PDF]
Mohammad Sadiq, Razia Aman, Khalid Saeed, M. Sohail Ahmad, M. Abid Zia
Modern Research in Catalysis (MRC) , 2015, DOI: 10.4236/mrc.2015.42006
Abstract: Linear amino acids covalently supported on graphene sheet were employed as catalysts for asymmetric aldol reactions between cyclohexanone and aldehydes (aliphatic and/or aromatic) in a batch type reactor in the presence of water. The reactions were found to exhibit high yield as well as excellent ee value. Additionally, the catalysts were found to be truly heterogeneous and eco-friendly.

The basic blocks of the universe matter: Boltzmann fundamental particle and energy quanta of dark matter and dark energy  [PDF]
Murad Shibli, Sohail Anwar
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.39099
Abstract: Recent astronomical NASA observations indicates that visible matter contributes only to about 4% of the universe total energy density, meanwhile, dark matter and dark energy contributes to 26% and 70% of the universe total energy, respectively, with an average density close to 10–26 kg/m3. This paper proposes an equation of state of dark energy and dark matter as one unified entity. This equation is derived based on the ideal gas equation, Boltzmann constant, Einstein energy-mass principle and based on the assumption that dark energy and dark matter behave as a perfect fluid. This analysis presents what could be the most fundamental particle and quanta of dark matter and dark energy. Considering NASA’s Cosmic Microwave Background Explorer (CMB) which estimated that the sky has an average temperature close to 2.7251 Kelvin, then the equivalent mass and energy of the proposed fundamental particle is determined. It is found that this candidate particle has an equivalent mass of 4.2141 × 10–40 Kg which is equivalent to 3.7674 × 10–23 J. Surprisingly, this value has the same order of Boltzmann constant KB = 1.38 ×10–23 J/K. This candidate particle could be the most fundamental and lightest particle in Nature and serves as the basic block of matter (quarks and gluons). Moreover, assuming a uniform space dark energy/dark matter density, then the critical temperature at which the dark matter has a unity entity per volume is determined as 34.983 × 1012 K. Analytically, it proposes that at this trillion temperature scale, the dark matter particles unified into a new quark-hydron particle. Finally, tentative experimental verification can be con ducted using the Relativistic Heavy Ion Collider (RHIC).
