Research ArticleOpen accessIn the abstractArithmetic Encoding Based Dynamic Source Routing for Ad-Hoc NetworksAjay Koul, R. B. Patel, V. K. BhatAn ad hoc network is a collection of mobile stations forming a temporary network without the aid of any centralized coordinator. Routing messages are an essential component of Mobile Adhoc Networks, as each packet needs to be passed quickly through intermediate nodes from source to destination. Internal threats due to changes in the node behaviour that target the routing discovery … …Journal of Computer Science, Vol. 4, Issue 5 · 31 May 2008 · 6,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractOperating System Support for Wireless Sensor NetworksAnt A. Fröhlich, Lucas F. WannerIn a wireless sensor network, several sensor nodes obtain local data and communicate among themselves in order to create a global vision of an object of study. The idea of a self-managed network of low-power, autonomous devices, that collects data from an environment and propagates information through a wireless link brought about several new challenges and requirements in application run-time … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 7,385 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormesis and Exercise: How the Cell Copes with Oxidative StressLi Li Ji, Zsolt Radak, Sataro GotoContraction-induced production of reactive oxygen and nitrogen species has been shown to cause oxidative stress to skeletal muscle, heart and other organs. As an adaptive response, muscle antioxidant defense systems are upregulated in response to exercise to restore intracellular prooxidantantioxidant homeostasis. Thus, both young and old animals and humans involved in regular exercise have shown reduced oxidative damage during acute … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,818 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Interventions in AgingSuresh I.S. RattanSingle or multiple exposure to low doses of potentially harmful agents can have a variety of anti-aging and longevity-extending hormetic effects. These hormetic stressors include irradiation, physical activity, food limitation, heat, hypergravity, dietary components and reactive oxygen species. Molecular mechanisms facilitating the hormetic effects are being elucidated and comprise a cascade of stress response and maintenance and repair pathways. Although … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractHormetic Triggers for Intervention in Aging, Disease and TraumaJoan Smith SonnebornHormesis refers to the ability of a chemical or physical agent to condition the physiological state of an organism to tolerate stress with low doses of otherwise harmful agents. Evolutionary evidence shows that the survival and longevity of species hinge on their optimal ability to resist stress challenge. Hormesis is a potent strategy to stimulate latent repair processes to tolerate … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractHIV-1 Infection and Drug-Abuse in India-An Emerging ChallengeMahendra Kumar, Adarsh M. Kumar, Raymond Ownby et al.India has a population of over 1 billion and the first cases of HIV-1 infection were reported from there in 1987. Since then HIV-infection has spread there very aggressively and at present it is reported that there may be 5.7 millions individuals infected with HIV. Unlike the western countries where the infected HIV-1 virus belongs to clade B, in India … …American Journal of Infectious Diseases, Vol. 3, Issue 4 · 31 Dec 2007 · 7,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractTopology Discovering and Power saving Mechanism for Routing in a Tree of Ad-hoc Wireless NetworksArwa ZabianPower management in mobile network is an open challenges where the power level in the network influences the network life time. However, there are a trade off between the power consumption and the connectivity in mobile networks. We present a topology control mechanism and a routing protocol for Ad-Hoc wireless networks that chooses the shortest path given the lower power … …Journal of Computer Science, Vol. 3, Issue 8 · 31 Aug 2007 · 6,555 accessesView PDFCite
Research ArticleOpen accessIn the abstractTask Load Balancing Strategy for Grid ComputingB. Yagoubi, Y. SlimaniWorkload and resource management are two essential functions provided at the service level of the Grid software infrastructure. To improve the global throughput of these environments, effective and efficient load balancing algorithms are fundamentally important. Most strategies were developed in mind, assuming homogeneous set of resources linked with homogeneous and fast networks. However for computational Grids we must address main … …Journal of Computer Science, Vol. 3, Issue 3 · 31 Mar 2007 · 7,609 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdaptive Hybrid Mobile Agent Protocol for Wireless Multihop Internet AccessA. Velmurugan, R. RajaramInternet-based Mobile Ad Hoc Networking (MANET) is an emerging technology that supports self-organizing mobile networking infrastructures. This is expected to be of great use in commercial applications for the next generation Internet users. A number of technical challenges are faced today due to the heterogeneous, dynamic nature of this hybrid MANET. A new hybrid routing scheme AODV_ALMA is proposed, which … …Journal of Computer Science, Vol. 2, Issue 9 · 30 Sep 2006 · 6,124 accessesView PDFCite
