Research ArticleOpen accessIn the abstractQuadrotor Obstacle Avoidance Based on Integral BacksteppingLianchuan Zhang, Young Baik Kim, Kil To ChongThis paper addressed obstacle avoidance problem of a quadrotor in outdoor environment. Path planning was finished by employing classical Dijkstra algorithm and the controller of the quadrotor adopted integral backstepping method. In order to get a smooth trajectory with time optimal and acceleration constraints properties, quantic polynomials were utilized to generate trajectory file. The scheme is particularly practical and useful … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 27 Jul 2016 · 6,981 accessesView PDFCite

Research ArticleOpen accessIn the abstractA MULTI ATTRIBUTE RANKING MECHANISM FOR PEER-TO-PEER NETWORKSSheila Anand, B. SwaminathanP2P systems are envisioned to play a greater role in collaborative applications. P2P environments remove the challenging task of using servers for information sharing. Emerging collaborative P2P systems require discovery and utilization of multi-attribute, distributed and dynamic group of resources to achieve greater tasks beyond conventional file and processor cycle sharing. The process of selection of a peer for collaborative … …Journal of Computer Science, Vol. 10, Issue 8 · 24 Feb 2014 · 6,879 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Chaotic Block Cipher for Real-Time MultimediaN. Radha, M. VenkatesuluProblem statement: The widespread use of image, audio and video data makes media content protection increasingly necessary and important. We propose a naive approach which treats the multimedia signal to be protected as a text and use proposed encryption design to encrypt the whole data stream. Upon reception, the entire cipher text data stream would be decrypted and playback can … …Journal of Computer Science, Vol. 8, Issue 6 · 27 Apr 2012 · 7,306 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordA 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 · 6,634 accessesView PDFCite
