Research ArticleOpen accessIn the author namesEnhanced RSACRT for Energy Efficient Authentication to Wireless Sensor Networks SecurityP. Kalyani, C. ChellappanProblem statement: The Security in WSN has become a challenge because of its inherent limitations of resources imposed on the sensor nodes. Authentication and key management scheme allows WSNs to be used with confidence and maintains integrity of data in sensor networks. Approach: In the WSN limited resource scenario the generation of public key done and are randomly pre distributed … …American Journal of Applied Sciences, Vol. 9, Issue 10 · 18 Aug 2012 · 7,344 accessesView PDF Cite

Research ArticleOpen accessIn the author namesSimplified Modeling, Analysis and Simulation of Permanent Magnet Brushless Direct Current Motors for Sensorless OperationE. Kaliappan, C. ChellamuthuProblem statement: In this study, a simplified modeling and experimental analysis of Permanent Magnet Brushless DC (PMBLDC) motors for Sensorless operation using MATLAB/SIMULINK. This model provides a mechanism for monitoring and controlling the voltage, current, speed and torque response. Approach: BLDC motor is modeled as sub-blocks. The inverter and switching function are implemented as S-function builder block. The Sensorless scheme … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 16 May 2012 · 7,648 accessesView PDF Cite

Research ArticleOpen accessIn the author namesA Multipath Energy Efficient Congestion Control Scheme for Wireless Sensor NetworkB. Chellaprabha, S. Chenthur PandianProblem statement: In most of the existing works either detection of congestion or scheme for congestion control in wireless sensor networks are presented. A very few works have been done, taken in to account of both congestion detection and congestion control. In most of the congestion detection works they have not achieved accuracy in detecting congestion and have resulted with … …Journal of Computer Science, Vol. 8, Issue 6 · 20 Mar 2012 · 6,860 accessesView PDF Cite

Research ArticleOpen accessIn the author namesIntelligent Model for Traffic Safety ApplicationsG. Nagappan, C. ChellappanProblem statement: This study presents an analysis on road traffic system focused on the use of communications to detect dangerous vehicles on roads and highways and how it could be used to enhance driver safety. Approach: The intelligent traffic safety application model is based on all traffic flow theories developed in the last years, leading to reliable representations of road … …Journal of Computer Science, Vol. 8, Issue 3 · 14 Jan 2012 · 6,727 accessesView PDF Cite

Research ArticleOpen accessIn the author namesHeart Rate Variability Analysis in Different Age and Pathological ConditionsM.E.S. Chelladurai, N. KumaravelProblem statement: Heart Rate Variability (HRV) has been used as a measure of mortality primarily with patients who had undergone cardiac surgery. The analysis of Heart Rate Variability (HRV) demands specific capabilities which are not provided either by parametric or nonparametric conventional estimation methods. The Empirical Mode Decomposition (EMD) adaptively estimates the Intrinsic Mode Functions (IMFs) of nonlinear nonstationary signals. … …Journal of Computer Science, Vol. 7, Issue 10 · 4 Aug 2011 · 6,822 accessesView PDF Cite

Research ArticleOpen accessIn the author namesAuthenticated 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 · 6,416 accessesView PDF Cite
