Research ArticleOpen accessIn the abstractStudy of Electronic Properties of Metal-Insulator-Metal Structures for Fabrication of Cold CathodesHossein Ghaforyan, Majid EbrahimzadehProblem statement: The electrical properties of thin film structures consisting of metalinsulator- metal sandwiches are important in electronic devices. Approach: The electrical properties of thin film structures consisting of metal-insulator-metal sandwiches are investigated in this experimental work. Results: We are discussed of the electroformed metal-insulator-metal structures Au-MgF2-Au and comparison with other Au-SiO/CeF3-Au, Cu-CeF3-Cu, Cu-SiO-Cu, Au-CeF3-Au specimens. There explains various properties … …Physics International, Vol. 1, Issue 2 · 12 Aug 2011 · 7,751 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Fast Handover Scheme for Multicasting in IPv6 based Mobile Ad hoc NetworksH. Parveen Sultana, M. Pounambal, Dr. P. Venkata KrishnaProblem statement: In the previous researches, steps were taken to resolve the problems of multicasting, after several discussions. Actually these issues were raised, while multicasting packets from Internet Protocol (IP) to Mobile Nodes (MN). On the other hand, there is very little concern about the problem of packet loss reduction. Sometimes the occurrence of multicast service chaos is ignored during … …Journal of Computer Science, Vol. 7, Issue 1 · 16 Dec 2010 · 7,241 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA New Type of Network Security Protocol Using Hybrid Encryption in Virtual Private NetworkingE. Ramaraj, S. KarthikeyanToday wireless communications is acting as a major role in networks. Through year-end 2006, the employee's ability to install unmanaged access points will result is more than 50% of enterprises exposing sensitive information through the wireless virtual private networks (VPN). It enables you to send the data between two computers across a shared or public network in a manner that … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,788 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn using Mobile IP ProtocolsFayza A. NadaThe recent advances in wireless communication technology and the unprecedented growth of the Internet have paved the way for wireless networking and IP mobility. Mobile Internet protocol has been designed within the IETF to support the mobility of users who wish to connect to the Internet and maintain communications as they move from place to place.

Research ArticleOpen accessIn the abstractHome Agent Architecture and Algorithms for Mobility Management in Mobile IP NetworksMarcellin Diha, Samuel PierreThis study proposes new Home Agent architecture and algorithms for real-time mobility management in mobile IP networks. The proposed architecture and algorithms offer a better performance based on the call-to-mobility ratio (CMR) and require less time for the location update and the tunneling compared with the Mobile IP model. These results are very useful and interesting for a real-time context … …Journal of Computer Science, Vol. 2, Issue 1 · 31 Jan 2006 · 6,899 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOn Analysis and Design of the Enhanced Firewall for Intranet SecurityU. K. Singh, A. K. Ramani, N. S. ChaudhariIntranet often employ an Internet firewall to mitigate risks of system penetration, data theft, data destruction and other security breaches. Conventional Internet firewalls impose an overly simple inside vs. outside model of security that is incompatible with many business practices that require extending limited trust to external entities. Additionally, firewall security perimeters are somewhat weak: they provide no protection from … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,709 accessesView PDF Cite
