Research ArticleOpen accessIn the abstractAccelerating Digital Forensics through Parallel ComputingGhada Elkabbany, Mohamed Rasslan, Heba AslanDigital crimes in the era of big data and cloud computing imposes significant challenges in digital forensics. Cloud environment provides low cost, easy management and reasonable solutions. Moreover, it supports big data structures and solutions (i.e., security, privacy and digital forensics). In order to achieve a secure digital forensics analysis in cloud environment, researchers have proposed solutions with expensive communication … …Journal of Computer Science, Vol. 14, Issue 2 · 20 Feb 2018 · 8,035 accessesView PDFCite
Research ArticleOpen accessIn the abstractSecurity in MANET’s by Using Detective Signature TechniquesGayathri A., P. NarayanasamyMobile Ad-hoc Network (MANET) is one among the fastest growing area in the field of research where security is a vital factor for protecting MANET against attacks, EAACK is an acknowledgement based IDS which is composed of three parts namely, ACK, S-ACK and MRA along with digital signature to provide security against attacks. Till now contemporary technique such as EAACK … …Journal of Computer Science, Vol. 11, Issue 3 · 21 Apr 2015 · 6,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractASYNCHRONOUS TIME ENCODER BASED QUASI-STATIC MODELLING FOR HUMAN AREA NETWORK IN VANETR. Vimal Karthick, G. S. Raj, R. Srinivasan et al.Power constraints play a key role in designing Human Area Networks (HANs) for bio authentication vehicle based on driver's identity. To alleviate the power constraints, we advocate a design that uses an asynchronous time encoding mechanisms for representing bio authentication information and the skin surface as the communication channel. Time encoding does not require a clock while allows perfect signal … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,060 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpectrum Switchover for Commercial use and "Spectrum Procurement" ContestAlexander RymanovMotivated by the need to implement wireless broadband mobile communications (Long Term Evolution (LTE)) in the "Digital Dividend" band (790-862 MHz) in Russia and to relocate government users of spectrum, especially the Aeronautical Radio Navigation Service (ARNS), this article focuses on the funding of organizational and technical measures to relocate government users from the spectrum and to transfer the spectrum … …American Journal of Applied Sciences, Vol. 11, Issue 11 · 10 Dec 2014 · 6,508 accessesView PDFCite
Research ArticleOpen accessIn the abstractAN IN-HOUSE COMPUTER-BASED DATA ACQUISITION AND CONTROL SYSTEM FOR ANAEROBIC FERMENTATION PROCESSESE. A. Echiegu, A. E. GhalyA computer-based Data Acquisition and Control System (DACS) capable of monitoring the temperature, pH and gas production as well as maintaining a pre-determined temperature profile and feeding regime in anaerobic reactors was developed and tested. The hardware for the DACS was a series-based system consisting of a host processor which drives three modules-a digital input mode (MODULE 255), an analog … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 3 · 17 Nov 2014 · 6,907 accessesView PDFCite
Research ArticleOpen accessIn the abstractPERFORMANCE OF TOPOLOGY AWARE RELIABLE ROUTING PROTOCOL FOR LARGE SCALE VIRTUAL PRIVATE NETWORKJayanthi Gokulakrishnan, V. Thulasi BaiA network which merges the usage of the public and the private networks and uses security software for the purpose of compressing, encrypting and masking the digital packets that are being transmitted in the network is called as Virtual Private Network (VPN). In VPN, the communication between the user ends is maintained such that it appears as if the source … …Journal of Computer Science, Vol. 10, Issue 9 · 23 Jun 2014 · 6,662 accessesView PDFCite

Research ArticleOpen accessIn the abstractSecond-Order Statistical Approach for Digital Modulation Scheme Classification in Cognitive Radio Using Support Vector Machine and K-Nearest Neighbor ClassifierS. Ravi, R. KannanCognitive radio systems require detection of different signals for communication. In this study, an approach for multiclass signal classification based on second-order statistical feature is proposed. The proposed system is designed to recognize three different digital modulation schemes such as PAM, 32QAM and 64QAM. The signal classification is achieved by extracting the 2nd order cumulants of the real and imaginary … …Journal of Computer Science, Vol. 9, Issue 2 · 11 Apr 2013 · 6,732 accessesView PDFCite
