Research ArticleOpen accessIn the abstractTacit Knowledge CodificationMarzanah A. Jabar, Fatimah Sidi, Mohd. Hasan SelamatProblem statement: In managing knowledge and competencies as a strategic advantage to an organization, there are difficulties in capturing, storing, sharing and reusing all this knowledge. Researchers have agreed that assessing tacit knowledge is difficult because knowhow of an employee are elusive and what more to assess them. It is compounded when employees leave the organization or become unavailable due … …Journal of Computer Science, Vol. 6, Issue 10 · 10 Aug 2010 · 10,218 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Causal Protocol with Forward Error Correction for Mobile Distributed SystemsEduardo Lopez Dominguez, Saul E. Pomares Hernandez, Gustavo Rodriguez Gomez et al.Problem statement: Causal ordering is used in Mobile Distributed Systems (MDS) to reduce the non-determinism induced by four main aspects: host mobility, asynchronous execution, unpredictable communication delays and unreliable communication channels. Some causal protocols have been proposed for MDS. All of these protocols in order to ensure the causal order in unreliable channels use the method of Automatic Repeat Request … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 8,239 accessesView PDFCite

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

ZukarnainThe aim of the discrete simulation framework is to deal with issues of the next generation of wireless cellular networks (e.g., multimedia traffic, radio resource management and mobility... etc) and to provide a platform for current and future investigations involving wireless cellular networks. The simulator is built from the scratch to enable customization requirements of any research and to provide … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,070 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Approach to Modeling and Flooding in Ad-hoc Wireless NetworksO. Issaad, S. Pierre, G. I. Ivascu, O. GarciaThis study proposes a new modeling approach for wireless ad-hoc networks. The new approach is based on the construction of fuzzy neighborhoods and essentially consists of assigning a membership or importance degree to each network radio link which reflects the relative quality of this link. This approach is first used to model the flooding problem and then an algorithm is … …Journal of Computer Science, Vol. 4, Issue 12 · 31 Dec 2008 · 7,015 accessesView PDFCite
