Minimizing the Overhead caused due to dynamic nodes in Mobile Ad-hoc Networks using Zone routing protocol

Opportunistic data forwarding has become a interesting topic in the multi-hop wireless networking. Opportunistic data forwarding is not used in mobile ad hoc networks (MANETs) due to the lack of an efficient lightweight proactive strong source routing scheme. Proactive Source Routing uses Breadth First Spanning Trees (BFSTs) and maintains more network topology information to facilitate source routing. Although it has greatly reduced overhead than traditional link state (LS)-based routing protocols and reactive source routing protocols, the computational and memory overhead involved in maintaining BFSTs to reach every node in the denser networks will be high. In this paper Zone-based Proactive Source Routing Protocol is proposed. Zone routing protocol (ZRP) uses partition based routing. The ZRP make use of source routing inside a zone and on-demand routing outside the zone. This approach combines the advantages of both proactive and zone based routing protocols. The simulation shows that the Z-PSR i.e. zone based proactive source routing protocol performs better compared to PSR

The data paper: a mechanism to incentivize data publishing in biodiversity science

<p/> <p>Background</p> <p>Free and open access to primary biodiversity data is essential for informed decision-making to achieve conservation of biodiversity and sustainable development. However, primary biodiversity data are neither easily accessible nor discoverable. Among several impediments, one is a lack of incentives to data publishers for publishing of their data resources. One such mechanism currently lacking is recognition through conventional scholarly publication of enriched metadata, which should ensure rapid discovery of 'fit-for-use' biodiversity data resources.</p> <p>Discussion</p> <p>We review the state of the art of data discovery options and the mechanisms in place for incentivizing data publishers efforts towards easy, efficient and enhanced publishing, dissemination, sharing and re-use of biodiversity data. We propose the establishment of the 'biodiversity data paper' as one possible mechanism to offer scholarly recognition for efforts and investment by data publishers in authoring rich metadata and publishing them as citable academic papers. While detailing the benefits to data publishers, we describe the objectives, work flow and outcomes of the pilot project commissioned by the Global Biodiversity Information Facility in collaboration with scholarly publishers and pioneered by Pensoft Publishers through its journals <it>Zookeys</it>, <it>PhytoKeys</it>, <it>MycoKeys</it>, <it>BioRisk</it>, <it>NeoBiota</it>, <it>Nature Conservation</it> and the forthcoming <it>Biodiversity Data Journal</it>. We then debate further enhancements of the data paper beyond the pilot project and attempt to forecast the future uptake of data papers as an incentivization mechanism by the stakeholder communities.</p> <p>Conclusions</p> <p>We believe that in addition to recognition for those involved in the data publishing enterprise, data papers will also expedite publishing of fit-for-use biodiversity data resources. However, uptake and establishment of the data paper as a potential mechanism of scholarly recognition requires a high degree of commitment and investment by the cross-sectional stakeholder communities.</p

Ferrule-top nanoindenter: An optomechanical fiber sensor for nanoindentation

Ferrule-top probes are self-aligned all-optical devices obtained by fabricating a cantilever on the top of a ferruled optical fiber. This approach has been proven to provide a new platform for the realization of small footprint atomic force microscopes (AFMs) that adapt well to utilization outside specialized laboratories [D. Chavan, Rev. Sci. Instrum. 81, 123702 (2010)10.1063/1.3516044; D. Chavan, Rev. Sci. Instrum. 82, 046107 (2011)10.1063/1.3579496]. In this paper we now show that ferrule-top cantilevers can be also used to develop nanoindenters. Our instrument combines the sensitivity of commercial AFM-based indentation with the ease-of-use of more macroscopic instrumented indenters available today on the market. Furthermore, the all-optical design allows smooth operations also in liquids, where other devices are much more limited and often provide data that are difficult to interpret. This study may pave the way to the implementation of a new generation user-friendly nanoindenters for the measurement of the stiffness of samples in material sciences and medical research. © 2012 American Institute of Physics

Carbon Modeling of Agroforestry Systems at Farmers’ Field in Indo-Gangetic Plains of India

The Indian Green revolution region “Indo-Gangetic Plain” (IGP) comprises of four agro-climatic zones namely lower, middle, upper, and trans gangetic plains covering West Bengal, Bihar, Uttar Pradesh, Delhi, Uttarakhand, Chandigarh, Haryana, Punjab, and some part of Rajasthan state. It covers 169 districts with total geographical area of 43.70 million ha. The Indo-Gangetic plains are one of the most populous regions with its area covering nearly 13% of the total geographical area of the country. It produces about 50% of the total food grains to feed 40% of the population. The continuous cropping of rice-wheat system has degraded the soil health dramatically over the years. Hence, the incorporation of trees in agriculture would be a better option to improve the soil as well as livelihood of the farmers in IGP. Agriculture is the major enterprise of the region that is most vulnerable to climate changes particularly owing to the inadequacy of resources with the smallholder farmers. While, agroforestry has the potential to play a significant role in mitigating the atmospheric accumulation of greenhouse gases (GHG), it also helps smallholder farmers adapt to the changes. These are the reasons for recognizing agroforestry as a viable alternative to prevent and mitigate climate change (Ram Newaj et al., 2014). A considerable proportion of agroforestry area located in IGP and some of the promising tree species like Populus deltoides, Eucalyptus tereticornis, Melia azadirach, Mangifera indica, Dalbergia sissoo, and Acacia nilotica are very common in the farmer’s fields. Keeping this in view, the field survey was carried out to estimate the carbon sequestration potential at a farmer’s field in IGP

Developing Post Rainy Sorghum Seed System in India

The crops grown under rainfed agriculture are described as farming practices that rely on rainfall for crop production and their seed systems describe, how farmers in these regions are sourcing seed for cultivating these crops. The objective of this chapter is to share information, experiences and some success stories of seed value chain models developed for production and supply of improved varieties to resource poor farmers to enhance production of rainfed crops. Majority of crop varieties grown under rainfed agriculture system are open pollinated varieties or self-pollinated crops especially food crops, cereals and legumes grown in semi-arid tropics of the globe. The importance of rainfed agriculture varies regionally but produces most food for poor communities in developing countries. In sub-Saharan Africa more than 95 per cent of the farmed land is rainfed, while the corresponding figure for Latin America is almost 90 per cent, for South Asia about 60 per cent, for East Asia 65 per cent and for the Near East and North Africa 75 per cent..
