Pollution attacks refer to ones where attackers modify and inject corrupted data packets into the wireless network with network coding to disrupt the decoding process. In the context of network coding, the epidemic effect of pollution attacks can degrade network throughput significantly because of the mixing nature of network coding. To address this issue, a number of schemes to identify malici...

Qualitative status of the environment is signaled by a group of indicators, known as bioindicators, several of which are responsible for showing progressive impacts of different types of pollutants. Having addressed the influence of various bioindicators in environmental pollution, it has been revealed that bioindicators are sensitive to any disturbance in any environment. With regards to the p...

one of the most important issues in today&rsquos; urban world is increasing use of cars and its noise pollution, which is now one of the most important affecting pollutants on health and quality of lives of residents in urban areas. noise pollution effects on various aspects of human and the community health as well as the high cost of treatment, thus more studies in this field is needed. hence...

BACKGROUND Cost-benefit analysis is a transparent tool to inform policy makers about the potential effect of regulatory interventions, nevertheless its use to evaluate clean-up interventions in polluted industrial sites is limited. The two industrial areas of Gela and Priolo in Italy were declared "at high risk of environmental crisis" in 1990. Since then little has been done to clean the pollu...

The air pollution-related health benefits of interventions to reduce indoor air pollution from cooking and heating with solid fuels are evaluated in South and South-east Asia, Africa, and the Americas using generalized cost-effectiveness methodology. Three scenarios are assessed: 1) providing access to cleaner fuels, (2) providing access to improved stoves, and (3) providing part of the populat...

Nonpoint-source pollution remains a troubling source of water quality problems despite decades of economics research on the matter. Among the chief difficulties for addressing the issue are the property rights assignments implicit in the current policy environment that favor agricultural nonpoint-source pollution, the unobservability of field-level emissions, and complex fate and transport rela...

Worldwide, more than three billion people cook with wood, coal and other solid fuels on open fires or traditional stoves, contributing to more than 1.5 million deaths annually and a multitude of negative economic and environmental impacts. The aim of this article is to present the costs and benefits of interventions to reduce indoor air pollution by halving the global population currently lacki...
