Research ArticleOpen accessIn the abstractA Secure Time-Stamp Based Concurrency Control Protocol For Distributed DatabasesShashi Bhushan, R. B. Patel, Mayank DaveIn distributed database systems the global database is partitioned into a collection of local databases stored at different sites. In this era of growing technology and fast communication media, security has an important role to play. In this paper we presented a secure concurrency control protocol (SCCP) based on the timestamp ordering, which provides concurrency control and maintains security. We … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,885 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAn Effective Key Management Approach to Differential Access Control in Dynamic EnvironmentsYogesh Karandikar, Xukai Zou, Yuanshun DaiApplications like e-newspaper or interactive online gaming have more than one resource and a large number of users. There is a many-to-many relationship between users and resources; each user can access multiple resources and multiple users can access each resource. The resources are independent and each resource needs to be encrypted by a different Resource Encryption Key (REK). Each REK … …Journal of Computer Science, Vol. 2, Issue 6 · 30 Jun 2006 · 6,770 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInformation Protection in Academic Campuses: A Scalable FrameworkD. S. Bhilare, A. K. Ramani, S. TanwaniProblem statement: Most institutions recognize the critical role that information security risk management plays in supporting their missions and objectives. Often, institutions do not pay enough attention towards assessing effectiveness of existing security measures. They are also unable to respond to new security threats in reasonable time. Furthermore, new laws are also forcing institutions to manage security risk more closely … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,872 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIrregular Class of Multistage Interconnection Network in Parallel ProcessingSandeep Sharma, K. S. Kahlon, P. K. Bansal, Kawaljeet SinghA major problem in designing a large-scale parallel and distributed system was the construction of an Interconnection Network (IN) to provide inter-processor communication. One of the biggest issues in the development of such a system was the development of an effective architecture and algorithms that have high reliability, give good performance (even in the presence of faults), low cost, low … …Journal of Computer Science, Vol. 4, Issue 3 · 31 Mar 2008 · 7,057 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSolving Traffic Routing System using VANet Strategy Combined with a Distributed Swarm Intelligence OptimizationElgarej Mouhcine, Khalifa Mansouri, Youssfi MohamedProposing an efficient strategy to reduce traffic congestion is an essential step towards improvement as we take into consideration the unpredictable and dynamic infrastructure of the road network. With the advances in computing technologies and communications protocols, we can retrieve any type of data and receive in real-time the state of traffic congestion at each road using Electronic Toll Collection … …Journal of Computer Science, Vol. 14, Issue 11 · 12 Nov 2018 · 7,592 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEnergy Aware Multiple Constraints Quality of Service Routing Protocol with Dynamic Mobility Prediction for Mobile Ad hoc NetworksSenthilkumar Maruthamuthu, Somasundaram SankaralingamProblem statement: This study presents a source based reactive protocol called "Energy Aware Multiple Constraints QoS Routing Protocol with Dynamic Mobility Prediction (EMQRPDM)" for MANET. It is an enhanced version of our previous protocol called "Power aware multiple QoS constraints routing protocol with mobility prediction (PMQRPMP)". It addresses the issues such as routing, mobility and power management in MANET. Approach: … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,477 accessesView PDF Cite
