Research ArticleOpen accessIn the abstractHybrid Approach for Detection and Recognition of VehiclesK. S. Selvanayaki, Rm. SomaSundaramOn road vehicles have increased in numbers and monitoring them is a challenging task. In common areas of public crowd people and vehicles are common objects for monitoring. The proposed system aims at detecting number plate information indicating the possibility for security relevant issues. Existing system performs recognition mainly by using license plate alone. Addition of the features (logo, colour, … …Journal of Computer Science, Vol. 11, Issue 2 · 6 Sep 2014 · 7,436 accessesView PDF Cite

Research ArticleOpen accessIn the abstractSOPC BASED WIRELESS REMOTE PATIENT MONITORING USING ULTRA LIGHTWEIGHT CRYPTOGRAPHYA. Arun, P. Nirmal KumarRemote Patient Monitoring (RPM) provides flexible and powerful patient surveillance through wearable devices at anytime and anywhere. This can be achieved by using a Body Sensor Network (BSN), which is deployed on a human body for monitoring the healthcare. The mobile healthcare management with increased feasibility and handiness introduced several noteworthy challenges for the provider, policy makers, patient and hospitals. … …Journal of Computer Science, Vol. 10, Issue 10 · 8 May 2014 · 7,198 accessesView PDF Cite

Research ArticleOpen accessIn the abstractKEY FACTORS FOR IMPROVING TECHNICAL EFFICIENCY OF UPLAND RICE PRODUCTIONThanaporn Athipanyakul, Panusak Jitsaeng, Napa Pongkapan, Piansak PakdeeFood security problems are major issues in developing countries, especially under the conditions of restricted farm resources and environmental degradation. The re-allocation of existing farm resources in the upland in order to reach a production of maximum output under given technologies and the estimated value of the technical efficiency have been important information for this purpose. The objective of this … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 24 Dec 2013 · 7,291 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOverview on Key Distribution Primitives in Wireless Sensor NetworkM. Raghini, N. Uma Maheswari, R. VenkateshOwing to the security requirements of wireless sensor network, the background of Wireless Sensor Network (WSN) is to be analyzed with different threats and attack models. Physical compromising of sensor nodes by an adversary is an emerging problem in sensor network and accordingly, it is necessary to provide an environment with efficient key management techniques due to resource constraints on … …Journal of Computer Science, Vol. 9, Issue 5 · 17 May 2013 · 6,183 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPrevention of Spoofing Attacks in the Infrastructure Wireless NetworksWesam S. Bhaya, Samraa A. AlAsadyProblem statement: Spoofing Attack is one of the vulnerabilities in the wireless networks, which is a situation in which the intruder successfully masquerades as legal one. Spoofing Attacks will decrease the performance of the network and violate many security issues. In the networks that use MAC address based filtering approach to authenticate the clients, the spoofer just needs to get … …Journal of Computer Science, Vol. 8, Issue 10 · 4 Sep 2012 · 7,844 accessesView PDF Cite

Research ArticleOpen accessIn the abstractOptical Code-Division Multiple-Access and Wavelength Division Multiplexing: Hybrid Scheme ReviewHesham A. Bakarman, P. Susthitha Menon, Isaac A.M. Ashour, Sahbudin ShaariProblem statement: Hybrid Optical Code-Division Multiple-Access (OCDMA) and Wavelength-Division Multiplexing (WDM) have flourished as successful schemes for expanding the transmission capacity as well as enhancing the security for OCDMA.

Research ArticleOpen accessIn the abstractA Stringent Authorization using Principles and Policy for Grid ComputingA. R. Jayasudha, T. PurusothamanProblem statement: The current information security mechanisms are insufficient to address authorization issues. The access control models today are mostly static and they are not wellsuited for the service-oriented environments where information access is dynamic in nature. Traditional authorization security techniques do not directly address these concerns as they primarily use access control lists for authorization, where the user whose … …Journal of Computer Science, Vol. 7, Issue 8 · 8 Aug 2011 · 6,638 accessesView PDF Cite
