Research ArticleOpen accessIn the abstractAuthenticated Broadcast in Heterogeneous Wireless Sensor Networks using Chinese Remainder Theorem AlgorithmKalyani Palanisamy, ChellappanProblem statement: The security in Wireless Sensor Networks (WSN) is a critical issue due to the inherent limitations of computational capacity, storage capacity and power usage. Key management only makes sure the communicating nodes possess the necessary keys, at the same time protecting the confidentiality, integrity and authenticity of the communicated data. Approach: Proposed a RSA-CRT methodology for authenticated broadcast … …Journal of Computer Science, Vol. 7, Issue 6 · 14 Jun 2011 · 6,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractAuthentication Based and Optimized Routing Technique in Mobile Ad hoc NetworksS. Varadhaganapathy, A. M. Natarajan, S. N. SivanandamProblem statement: An Ad hoc network has been defined as a self-organizing, dynamic topology network formed by a group of wireless mobile nodes. Minimal configuration, absence of infrastructure and quick deployment, would make ad hoc networks convenient for emergency situations other than military applications. In recent years, security in Ad hoc Networks as a research topic had started to receive … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 6,903 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Robust Hybrid Approach to Enhance Speech in Mobile Communication SystemsManimegalai Govindan Sumithra, Keppana Gounder Thanuskodi, Bharathi DeepaProblem statement: The received voice signal in mobile communication is often disturbed by background noise and hence there is a need for good noise reduction methods for enhancing Speech. It is well known that denoising is a compromise between the removal of the largest possible amount of noise and the preservation of signal integrity. To address this issue, a new … …American Journal of Applied Sciences, Vol. 8, Issue 4 · 18 Apr 2011 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Disruption-Tolerant Model for Building a Mobile Application Using Web ServiceMaryati Mohd. Yusof, Mansor Omar, Zarina ShukurProblem statement: The emerging technology in broadband telecommunication and mobile devices has increased the use of mobile applications. However, the use of mobile application is affected with low bandwidth or disrupted broadband telecommunication due to building blockage or out of coverage area. Approach: We proposed a Disruption-Tolerant Mobile Application Model (DTMA) that enables remote data access and overcomes constraint due … …Journal of Computer Science, Vol. 6, Issue 12 · 1 Dec 2010 · 7,219 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolid Waste Characterization and Recycling Potential for University Technology PETRONAS Academic BuildingsAmirhossein Malakahmad, Muhammad Za’im Zaki bin Che Mohd Nasir, Shamsul Rahman Mohammed Kutty, Mohammed Hasnain IsaProblem statement: In many countries such as Malaysia, it is increasingly more difficult to find suitable locations for landfills, which are accepted by the population. These circumstances are to be found all over the world and make new strategies for waste management necessary. Approach: Integrated Solid Waste Management (ISWM) systems are one of the greatest challenges for sustainable development. But … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 8,867 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperiment of Tamper Detection and Recovery Watermarking in Picture Archiving and Communication SystemsSiau-Chuin Liew, Jasni Mohamad ZainProblem statement: Medical images such as x-rays, ultrasounds and Magnetic Resonance Imaging (MRI) plays an important role in helping the physicians to diagnose a disease or body conditions. These images can be tampered with existing image processing tools that is easily available. The usage of security measures such as watermarking can protect the integrity of the images. Numerous watermarking schemes … …Journal of Computer Science, Vol. 6, Issue 7 · 31 Jul 2010 · 7,651 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecurity Challenges in Multicast Communication for Mobile Ad Hoc NetworkS. Gunasekaran, K. DuraiswamyProblem statement: Multicasting communication network accepted a single message from an application and delivered copies of the message to multiple recipients at different locations. Recently, there has been an explosion of research literature on multicast communication environment. The objective of this study were to contribute the complexity of supporting current multicast applications, (i) the lack of reliable multicast transport mechanisms … …Journal of Computer Science, Vol. 6, Issue 5 · 31 May 2010 · 6,125 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Trust System Based on Multi Level Virus DetectionYasmine H. Abdul-AmirProblem statement: As these detection methods were developed and implemented, the virus developers adapted to the new detectors in ways intended to defeat them. Approach: This study introduced new multilevel virus detection (MDS). Results: This system model depended on an advance behavior blocking technology. It detected virus-code by a behavior approach monitors and determined a virus activity at several protection … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractMemory Storage Issues of Temporal Database Applications on Relational Database Management SystemsSami M. Halawani, Nashwan A. Al-RomemaProblem statement: Many existing database applications manage time-varying data. These database applications are referred to as temporal databases or time-oriented database applications that are considered as repositories of time-dependent data. Many proposals have been introduced for developing time-oriented database applications, some of which suggest building support for Temporal Database Management Systems (TDBMS) on top of existing non-temporal DBMSs, while others … …Journal of Computer Science, Vol. 6, Issue 3 · 31 Mar 2010 · 7,731 accessesView PDFCite
Research ArticleOpen accessIn the abstractModified Center Interpolation Net for Classification of Composite Structures Tested Using Low Frequency Electronic TappingMahmoud Z. IskandaraniProblem statement: Most exhaustive NDT techniques require large capital equipment, are difficult to apply to complex geometric structures and, above all, are time-consuming to use and some take a considerable time to complete. As a solution to the problems associated with NDT applications, there is a need to establish an intelligent analysis system that supports a portable testing environment, which … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 7,108 accessesView PDFCite
