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 abstractDEDICATED TRUSTEE DETECTOR OF BLACK HOLES IN MANETSJ. Manoranjini, A. ChandrasekarMANET is developing the next generation wireless universe. However MANETS prove their performance only when routing is efficient. In this paper we propose a model of Dedicated Trust System (DTS) which aims in detecting the misbehaving nodes. We implement our DTD using zone routing protocol with trusted systems. We finally develop a reputation model with two new parameters trustee and … …Journal of Computer Science, Vol. 10, Issue 9 · 10 Apr 2014 · 6,338 accessesView PDFCite

Research ArticleOpen accessIn the abstractDesign of Hybrid Coupler Connected Square Array Patch Antenna for Wi-Fi ApplicationsA. Sahaya Anselin Nisha, T. JayanthyMicrostrip patch antennas being popular because of light weight, low volume, thin profile configuration which can be made conformal. Wireless communication systems applications circular polarization antenna is placing vital role. In this study we introduce a new technique to produce circular polarization. Hybrid coupler is directly connected to microstrip antenna to get circular polarization. Also gain is further increased by … …Journal of Computer Science, Vol. 8, Issue 11 · 19 Sep 2012 · 6,638 accessesView PDFCite
