Research ArticleOpen accessIn the abstractFORMAL VERIFICATION OF SAFETY MESSAGE DISSEMINATION PROTOCOL FOR VANETSM. A. Berlin, Sheila AnandThis paper presents a formal verification of a safety message dissemination protocol used in vehicular ad-hoc networks. It is proposed to use Road Side Units to broadcast road hazard information to vehicles travelling on highways. Quick dissemination of road hazard information, like road blocks, slippery roads and other obstacles can help to prevent road accidents and improve passenger safety. Formal … …Journal of Computer Science, Vol. 9, Issue 8 · 9 Jul 2013 · 6,858 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Dynamic Approach for Rate Adaptation in Mobile Adhoc NetworksPalaniammal Senniappan, Suganya SubramaniamA Mobile Ad hoc Network (MANET) is a collection of mobile nodes with no fixed infrastructure. The absence of central authorization facility in dynamic and distributed environment affects the optimal utilization of resources like, throughput, power and bandwidth. Rate adaptation is the key technique to optimize the resource throughput. Some recently proposed rate adaptations use Request to Send/Clear to Send … …American Journal of Applied Sciences, Vol. 10, Issue 6 · 8 Jun 2013 · 6,673 accessesView PDFCite
Research ArticleOpen accessIn the abstractγAminobutyrate B Receptors in Central Amygdaloid and Medial Amygdaloid Nuclei of Amygdala Modulate Aggression in Male RatsMahnaz Taherianfard, Zahed Abdolahi, Hamid Rajaian et al.One neurochemical system most consistently linked with aggression is the GABAergic system. The aim of the present investigation was to examine the effect of injection of baclofen (GABAB agonist) and CGP35348 (GABAB antagonist) in the Central Amygdaloid (CA) and Medial Amygdaloid (MA) nuclei of the amygdala on offensive aggression behavior in the animal model. Sixty six adult male rats weighing … …Neuroscience International, Vol. 3, Issue 1 · 3 Sep 2012 · 7,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractCan Soy Change Serum Estradiol Concentration in Neonate Ovariectomized Rat?Mahnaz Taherianfard, Mina Tadjali, Mohammad Ebrahim AstanehProblem statement: Phytoestrogens are plant derived compound found in a wide variety of foods, most notably soy. The purpose of this study was to assess the effect of soy isoflavones on circulating 17-β estradiol in neonate ovariectomized rat. Approach: Thirty, one day olds rats were used. Blood sample were collected after two months. 17-β estradiol was assayed by radioimmuno assay … …Current Research in Medicine, Vol. 3, Issue 1 · 21 Mar 2012 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractRealization of Fault Tolerant Routing Protocol for ZigbeeSharmila Sankar, SankaranarayananProblem statement: Increased use of handheld devices and sensor devices pose problems in existing routing protocols. The performance of the existing routing protocols deteriorates very much on these dense scenarios. Control overheads are very important parameter in deciding the performance of routing protocols, which are introduced during route discovery and maintenance process. Denser the network, higher is the control overhead … …Journal of Computer Science, Vol. 8, Issue 5 · 2 Mar 2012 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractArtificial Bee Colony based Energy Aware and Energy Efficient Routing ProtocolP. Visu, S. Koteeswaran, J. JanetProblem statement: Network becomes very important technology in the day to day life style of modern computer era, in which the wireless communication become very popular for the last few years. In the same manner, the other wireless network, i.e., ado network is very popular among the researchers in the past few decades. Approach: The Ad hoc networks are defined … …Journal of Computer Science, Vol. 8, Issue 2 · 19 Jan 2012 · 7,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of Performance in Elite Young Cross-Country Skiing: Classical Style Vs Skate SkiingFrancisco P.D. la Fuente, Carlos C. Otin, Luis M. Benito et al.Problem statement: The aim of this study was to assess the differences in the skiing performance of two skiing styles (classical style Vs. skate skiing), in a group of young high-level skiers. Approach: Four high-level male junior cross-country skiers from the Centre of Winter Sports of Aragon (Spain), were selected for this study that was developed during two competitions: 10 … …Journal of Social Sciences, Vol. 7, Issue 4 · 14 Sep 2011 · 8,820 accessesView PDFCite
Research ArticleOpen accessIn the abstractCollaborative Caching Architecture for Continuous Query in Mobile DatabaseMohamed Ahmed Elfaki, Hamidah Ibrahim, Ali Mamat, Mohamed OthmanProblem statement: Cooperative caching, which allows sharing and coordination of cached data among clients, is a potential technique to improve the data access performance and availability in mobile ad hoc networks. However, variable data sizes, frequent data updates, limited client resources, insufficient wireless bandwidth and client’s mobility make cache management faces many challenges. Approach: In this study, we propose a … …American Journal of Economics and Business Administration, Vol. 3, Issue 1 · 7 Jan 2011 · 8,875 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Methodology for Designing Radix-2n Serial-Serial MultipliersAbdurazzag Sulaiman AlmiladiProblem statement: The fast growth and increase in complexity of digital and image processing systems necessitate the migration from ad hoc design methods to methodological ones. Methodologies will certainly ease the trade off selection for those systems and shortens the design time. To increase those gained values and expand the searching space more appropriate methodologies need to be developed. Approach: … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,922 accessesView PDFCite
Research ArticleOpen accessIn the abstractBluetooth Wireless Network Authentication Using Radio Frequency Communication ProtocolGhossoon M. Waleed, M. Faizal, R. B. Ahmad et al.Problem statement: Bluetooth has emerged as very popular ad hoc network standard today. Bluetooth network applications include wireless synchronization, e-mail/internet/intranet access using local personal computer connections, hidden computing through automated applications and networking. Due to this ability, it is not impossible for the network to receive any attack. Approach: In this study, we developed an algorithm to build new software … …Journal of Computer Science, Vol. 5, Issue 9 · 30 Sep 2009 · 7,819 accessesView PDFCite
