Research ArticleOpen accessIn the abstractSecondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive RadioInderdeep Kaur Aulakh, Renu VigThe constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a change in regulation of radio spectrum. In cognitive radio networks a secondary user network is designed for efficiently using gaps in spectrum and not causing at the same … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulticast Node Communication Using Virtual Queue with Process SchedulingS. Sumalatha, G. Sreenivasulu, G. Uday Kiran BhargavaMulticast technique is used to transmit node data from one source node to many destination nodes simultaneously and establish a communication in the network. In multicasting communication, node network packet collision occurrence is a frequent problem in real time network system. The node packet collision avoidance using virtual queue with process scheduling is discussed in this study and proposed central … …Journal of Computer Science, Vol. 11, Issue 2 · 28 Jan 2015 · 6,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractRTOS IMPLEMENTATION OF NON-LINEAR SYSTEM USING MULTI TASKING, SCHEDULING AND CRITICAL SECTIONM. Sujitha, V. Kannan, S. RaviRTOS based embedded systems are designed with priority based multiple tasks. Inter task communication and data corruptions are major constraints in multi-tasking RTOS system. This study we describe about the solution for these issues with an example Real-time Liquid level control system. Message queue and Mail box are used to perform inter task communication to improve the task execution time … …Journal of Computer Science, Vol. 10, Issue 11 · 20 Dec 2014 · 8,098 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 abstractTRAFFIC CONTROLLED-DEDICATED SHORT RANGE COMMUNICATION: A SECURE COMMUNICATION USING TRAFFIC CONTROLLED DEDICATED SHORT RANGE COMMUNICATION MODEL IN VEHICULAR AD HOC NETWORKS FOR SAFETY RELATED SERVICESK. Chandramohan, P. KamalakkannanTo increase the road safety and secure communication among the vehicles in the network environment, Dedicated Short Range Communication (DSRC) is followed. Nowadays, research over DSRC is dramatically increased for enhancing the road safety applications. The main task of DSRC is to protect the vehicles by communicating the warning message regarding the vehicle changing conditions, traffic occurrence and dangers over … …Journal of Computer Science, Vol. 10, Issue 7 · 17 Jun 2014 · 6,857 accessesView PDFCite
Research ArticleOpen accessIn the abstractA REFINEMENT OF DIJKSTRA'S ALGORITHM FOR EXTRACTION OF SHORTEST PATHS IN GENERALIZED REAL TIME-MULTIGRAPHSSiddhartha Sankar Biswas, Bashir Alam, M. N. DojaThe networks of the present day communication systems, be it a public road transportation system or a MANET or an Adhoc Network, frequently face a lot of uncertainties in particular regarding traffic jam, flood or water logging or PWD maintenance work (in case of public road network), attack or damage from internal or external agents, sudden failure of one or … …Journal of Computer Science, Vol. 10, Issue 4 · 14 Dec 2013 · 7,260 accessesView PDFCite
Research ArticleOpen accessIn the abstractOPTIMIZING BATCH REKEYING INTERVAL FOR SECURE GROUP COMMUNICATION BASED ON QUEUING MODELA. Vasanthi, T. PurusothamanRapid growth of Internet spawns many group oriented multicast applications like Internet pay TV, news dissemination and stock quote system. The fortes of these applications are the support of dynamic, scalable group membership and group members are geographically divergent. As members of the group move in and out, an imperative cryptographic rekeying model should be applied to preserve the confidentiality … …Journal of Computer Science, Vol. 10, Issue 2 · 20 Nov 2013 · 6,456 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Hybrid Approach for Node Co-Operation Based Clustering in Mobile Ad Hoc NetworksC. Sathiyakumar, K. DuraiswamyA Mobile Ad-Hoc Network (MANET) is termed as a set of wireless nodes which could be built with infrastructure less environment where network services are afforded by the nodes themselves. In such a situation, if a node refuses to co-operate with other nodes, then it will lead to a considerable diminution in throughput and the network operation decreases to low … …Journal of Computer Science, Vol. 9, Issue 2 · 26 Mar 2013 · 6,964 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Chaotic Encryption TechniqueAncy Mariam Babu, K. John SinghDrastic growth in multimedia communication resulted to numerous security issues in the transmission of data. Moreover, the network used for the digital communication does not provide much security for the data transfer. During this time, tens of millions people using the internet options for essential communication and is being a tool for commercial field increased, So that security is an … …American Journal of Applied Sciences, Vol. 10, Issue 1 · 8 Jan 2013 · 7,206 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance Evaluation of Multicrypt Encryption MechanismRhymend Uthariaraj Vaidyanathan, Lydia Elizabeth Benjamin, John Prakash ArockiasamyMulticast communication allows a single message packet to be routed to multiple nodes simultaneously. Membership in a multicast group is dynamic, allowing nodes to enter and leave the multicast session. Besides the benefits, multicast communication presents the challenge of securing the communication. In order to preserve confidentiality the general encryption mechanism used for point to point communications are used.
