Analysis of Routing Protocols over VANET
No full textVehicular Ad-hoc Network (VANET) is a new network technology where the cars are used as mobile nodes to form a communication network. In VANET, routing protocols have a significant role in terms of the performance because they determine the way of sending and receiving packets between mobile nodes. In this paper, we examine and analyze the performance of Ad-hoc On-Demand (AODV), Ad-hoc On-demand Multipath Distance Vector (AOMDV), Dynamic Source Routing (DSR) and Destination-Sequenced Distance Vector (DSDV) routing protocols over two different traffic connections; TCP and Constant Bit Rate (CBR) using different speeds and packet sizes. The performance measurements; Packet Delivery Ratio, Average End to End Delay and Average Throughput are examined with respect to speed and packet size. The objective of this study is to find the best routing protocol over all circumstances. Based on our validated results, DSR performs the best among all evaluated protocols
Robust Heterogeneous Network to Support Multitasking
No full textDue to emerging technology, efficient multitasking approach is highly demanded. But it is hard to accomplish in heterogeneous wireless networks, where diverse networks have dissimilar geometric features in service and traffic models. Multitasking loss examination based on Markov chain becomes inflexible in these networks owing to rigorous computations is obligatory. This paper emphases on the performance of heterogeneous wireless networks based on multitasking. A method based on multitasking of the interrelated traffic is used to attain an approximate performance in heterogeneous wireless networks with congested traffic. The accuracy of the robust heterogeneous network with multitasking is verified by using ns2 simulations.http://arxiv.org/abs/1309.451

Although there are many standard conventional pharmacologic approaches to the control of high blood pressure available, concern about risk versus benefit in the use of antihypertensive drug therapy for patients with mild hypertension leads to the objective of this study. There is an increasing demand and interest in nonpharmacologic interventions and whether or not alternative management of hypertension is safe and effective. Recommendations for some nonpharmacologic approaches to the treatment of hypertension are investigated in this study. The pros and cons of nutritional interventions, exercise and biobehavioral treatments are discussed along with the use of botanical medicine for the safe and effective management and treatment of hypertension without the use of drugs. Basic Procedures: A review of literature on the effectiveness of nonpharmacologic management of hypertension and the adverse effects of long term antihypertensive drugs have been documented in a number of clinical studies, reviews and meta-analyses. For the purpose of this investigation, a systematic search and review of literature were conducted on 3 major online databases: UpToDate, PUBMED and the Natural Medicines Comprehensive Database. A systematic approach was used to search each database using relevant search criteria. Main Findings: Studies suggest that although the majority of patients will require drug therapy, non-pharmacological approaches are preferable if they can be used. Nonpharmacologic recommendations in the treatment of hypertension for which there appear to be sufficient requisite data include weight reduction for the obese, moderate sodium restriction (although this is controversial) and restriction of alcohol, dietary recommendations for healthy living and regular exercise. There is also sufficient evidence that supports the use of traditional botanical medicine for the treatment of cardiovascular disease including hypertension. Principal Conclusions: Non pharmacological management of hypertension has the potential of safely and effectively improving quality of life while avoiding the side effects of conventional treatment which can be life threatening. Despite the need for more studies and additional evidence of relative effectiveness of non-pharmaceutical management of hypertension, naturopathic doctors and most experts feel that healthy lifestyle changes including diet and exercise play one of the most important roles in many susceptible patients in the genesis and maintenance of hypertension. In addition, this investigation highlights the use of 3 potent traditional botanicals—Crateagus, Rauwolfia and Terminalis. Although these plants have been used in the treatment of heart disease for hundreds of years, current research methods shows us they can be utilized effectively in deadly modern day diseases, including ischemic heart disease, congestive heart failure, arrhythmias and last but not least—hypertension

They are in the air we breathe, the water we drink, and the food that we eat. Although the number of toxins that alter our physiology are immeasurable, there are a few that have been isolated that alter genes, and contribute to disease. According to Joseph Mercola, OD, the top ten environmental toxins today are polychlorinated biphenyls (PCBs), Pesticides, Mycotoxins, Phthalates, Volatile Organic Compounds (VOCs), Dioxins, Asbestos, Heavy metals, Chloroform, and Chlorine. The purpose of this literature review is to examine these toxins and the subsequent effect they have on the human body/the role they play in disease
Automatic Energy Saving (AES) Model to Boost Ubiquitous Wireless Sensor Networks (WSNs)
No full textWe deploy BT node (sensor) that offers passive and active sensing capability to save energy. BT node works in passive mode for outdoor communication and active for indoor communication. The BT node is supported with novel automatic energy saving (AES) mathematical model to decide either modes. It provides robust and faster communication with less energy consumption. To validate this approach, network simulator-2 (ns2) simulation is used to simulate the behavior of network with the supporting mathematical model. The main objective of this research is to remotely access different types of servers, laptops, desktops and other static and moving objects. This prototype is initially deployed to control MSCS [13] & [14] from remote place through mobile devices. The prototype can further be enhanced to handle several objects simultaneously consuming less energy and resources.http://arxiv.org/abs/1309.450

The myelin sheath is thought to be attacked by the body’s own immune system leading to many neurological effects. Conventional medicine has mostly used immune suppressing drugs to treat this disorder, but all drugs have side effects that can be even more deadly than the disorder itself. The purpose of this paper is to determine if there are truly safe and effective natural ways to prevent and treat multiple sclerosis. This paper demonstrates that there are many natural ways to prevent and treat multiple sclerosis. For example, prevention and treatments include heavy metal chelation, using lipoic acid, fish oil, quercetin, curcumin, DHEA, cannabis, Horse chestnut and Gotu kola, but perhaps the one single most important way to prevent multiple sclerosis is through the intake of adequate amounts of vitamin D during pregnancy and throughout one’s life. CCSVI and Centella in combination were only somewhat touched upon in this research paper, but may have an important link to the development and progression of this disorder
Various Diseases With Polarized TH1/TH2 Immunity and Methods of Modulating Those Branches of the Immune System

If you are the author of this work and desire to provide it open access or wish access removed, please contact the Wahlstrom Library to discuss permission.This paper addresses the issue of the etiology of certain diseases believed to be caused by an imbalance in the TH1/TH2 immune system. Various databases were used to search for the studies cited in this review of literature and the allocation of research divided into either the TH1 or TH2 category. Overall, the studies presented in this paper support the premise that many diseases of the auto-immune or allergy categories seem to have an etiology stemming from an immune system that is skewed to either the TH1 or TH2 arm. Furthermore, other research has showed that by using different substances to modulate the overactive arm or to up-regulate the suppressed arm, the clinical symptoms of the disease can be improved or decreased. Although many of the studies done were performed on mice, this research can be a helpful tool in the management of these diseases in the human population
