Research ArticleOpen accessIn the abstractAnalytic Performability Model of Vertical Handoff in Wireless NetworksGowrishankar, G. N. Sekhar, P. S. SatyanarayanaProblem statement: The next generation wireless systems should be designed to support heterogeneous traffic with seamless mobility. A single network alone cannot cope up with such heterogeneous requirements. Hence it is desirable to interoperate between diverse and complementary Radio Access Technologies (RATs). In such system, user will switch between different Radio Access Technologies (RATs) to satisfy the User/application requirement and … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,230 accessesView PDFCite

Denial of Service (DoS) attack is the most current challenging issue on the WLANs. The objectives of the study were to (i) Provide an empirical analysis to conduct a series of wireless virtual carrier sense DoS attacks using wireless control frames vulnerabilities, (ii) Design a testbed to … …Journal of Computer Science, Vol. 5, Issue 3 · 31 Mar 2009 · 7,650 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Non-Exchanged Password Scheme for Password-Based Authentication in Client-Server SystemsShakir M. Hussain, Hussein Al-BahadiliThe password-based authentication is widely used in client-server systems. This research presents a non-exchanged password scheme for password-based authentication. This scheme constructs a Digital Signature (DS) that is derived from the user password. The digital signature is then exchanged instead of the password itself for the purpose of authentication. Therefore, we refer to it as a Password-Based Digital Signature (PBDS) … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,002 accessesView PDFCite
Research ArticleOpen accessIn the abstractDensification Behaviour of a Red Firing Tunisian Triassic ClayHajer Baccour, Mounir Medhioub, Fakher Jamoussi, Taher. MhiriInvestigations were undertaken to assess the thermal modification in clay products from Triassic sedimentary deposits. This study deals with the mineralogical, physico-chemical, thermal analysis and faience making attributes of representative Triassic clay in the south-Eastern Tunisia. The data collected from these techniques show that illite and kaolinite are the major clay phases. The accessory minerals detected in powdered rock are; … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,109 accessesView PDFCite
