In Wireless Nano-networks (WNNs), nodes are of nano-metric size and can be potentially dense in terms of neighbouring nodes. (...) The present study reveals the usefulness of implementing the sleeping mechanism in heterogeneous networks, as well as configuring a dynamic awaken duration for nodes based on a density estimation algorithm. We also proposed an algorithm that helps in increasing the reliability of the packet received by the destination node.

BIG DATA FOR GOOD: CAN BIG DATA ILLUSTRATE THE CHALLENGES FACING SYRIAN REFUGEES IN LEBANON?
The features of these tiers allow developers to automate many actions on Twitter, such as searching tweets, monitoring an account’s activity, real-time tweet streaming, advertising on Twitter and automating direct messages.15 In addition to the APIs created by Twitter and specially made for developers, multiple open source packages16 are available that allow scraping for tweets based on specific keywords, topics, locations and hashtags. 3. GDELT 4. (...) Examples include predicting sociodemographic indicators such as population density and economic indicators such as poverty levels. (...) The authors of “Dynamic population mapping using mobile phone data”23 use a dataset consisting of more than 1 billion CDRs from Portugal and France to estimate the population density at a national and seasonal scale. They show that not only can a population map be constructed via CDR population estimation, but this type of estimation based on daily phone records can show population dynamics.

For example, Programmable object interfaces and devices can be leveraged to allow the farmers to evaluate the soil conditions, moisture level, livestock feed levels density and level of pest control. For example, if the level of pest control exceeds prescribed range, through sensors alarm and alerts can be generated to warn the farmers to take actions. The purpose of “Smart Farming” is to increase the quality and quantity of agricultural production by using sensing technology to make farmers more intelligent and more connected in Indian Sub continent also across the globe. Keywords: ICT, Sustainable Agriculture, Precision Farming, Smart Cities, Ecosystem.

Plant Production and Protection Division: Interactions within soil communities english FAO Home Plant Production and Protection Division Thematic sitemap Information Resources News, Events, Bulletins in Keywords Contacts NSP - Interactions within soil communities   Any community of organisms which is made up of a population of different species there is opportunity for the organisms to interact with each other (Bianchi and Bianchi, 1995). If you consider two different populations living with each other, one of the interactions may occur (see opposite): Which interaction occurs would depend on the nature of the resources (type and level of food and energy supply), the population density and diversity. For example commensalism favours communities with high diversity whereas neutralism is more likely in communities with a low number of individuals.

Each one of these dimensions is also a construct, which can be measured in a number of ways. Keywords: measure of compactness, measuring sprawl, spatial dimensions, pattern of urban development, land use. (...) Intensity of land or space use — refers to the density dimension 8. As note Torrens and Alberti (2000), there is little agreement in the literature about density specification with regards to: what variable (activity) to use – housing units, population, or employment; at which scale to study – metropolitan area, city district, or neighborhood; over which geography to measure – total area (gross density), or area designate for residence (net density). 9. (...) The second approach includes calculation of density attenuation based on urban population density functions, and calculation of fractal dimension (see Batty and Kwang (1992) and Mesev et al., (1995) for the detailed discussion).
