As the technology gets advanced so as the security issues come into the picture. Here we will discuss about one such advancement in the modern world for communication purpose which is ruled by wireless networking. Precisely MANET (Mobile Adhoc Network) plays a huge role in transmission of data without any wired structure. Its distinct nature of maintaining the nodes and links to transmit the data at faster rate has proven its importance in communication media. The major issue with mobile adhoc network is security, there are two major such type of security issues which affects the MANET while transmitting data are Black hole and Gray hole attacks. This paper proposes Bulwark-AODV which prevents single or cooperative Black hole attacks by identifying malicious route replies at source and intermediate nodes and finds a shortest valid path. It also works in case of single adjacent node to the source and when there are multiple Black holes in the network. It detects Gray holes by snooping the ACKs of data packets. Forgery of ACK if any is identified by the source through checking the return time of ACK. Simulation results indicates better performance even though special cases are considered. © 2015 IEEE.

Computer Science and Engineering (CSE) and Information Technology (IT) students are not adequately exposed to implementing a software development methodology or a project management framework to develop software as per the current curriculum. The students' final year Project Work was selected to apply an industry-oriented Agile software development methodology. Specifically, we employed the most popular Agile project management and development framework called Scrum. Wiki pages were used to convey our expectations to students regarding project work. They were used as a collaborative tool by the team members during project implementation. In this paper, we present our experiences and lessons learned from applying the Scrum framework and using a collaborative Web 2.0 tool called Wikispaces in managing students' major projects. © 2015 IEEE.

Problem statement: Electromagnetic Radiation from mobile hand set is identified as one of the side effects for increasing rate of brain tumor. Due to this reason, Mobile phone industries are attentive towards safety issues of human health. Specific Absorption Rate is one of the important parameter while modeling the radiation effect on human head. Brain material with homogeneity is treated as an equivalent model of human head. The radiation caused by antennas mounted on mobile set is assumed to be monopolar. Approach: Apart from the Specific Absorption Rate, period of exposure to radiation is an extremely important parameter while assessing the effects on brain tissue. Correlation between the amount of radiation versus spherical model of brain is a complex phenomena, addressed in various simulation models. In the present work the field distribution inside the head are modeled using Dyadic Greens Functions while describing the effect of radiation pattern. Multilayered homogeneous lossy spherical model is proposed as an equivalent to head. Results: In this paper we present the depth of penetration of radiation and its effect on brain tissue. In essence the amount of electromagnetic power absorbed by biological tissues for various exposure conditions and types of emitting sources, utilizing a detailed model of the human head. Conclusion: Bio-heat equation is used to predict heat distribution inside the brain when exposed to radiation. The medium is assumed to be homogeneous, isotropic, linear, non dispersive and stationary. A critical evaluation of the method is discussed. © 2011 Science Publications.

Purpose: The PathVisio-Validator plugin aims to simplify the task of producing biological pathway diagrams that follow graphical standardized notations, such as Molecular Interaction Maps or the Systems Biology Graphical Notation. This plugin assists in the creation of pathway diagrams by ensuring correct usage of a notation, and thereby reducing ambiguity when diagrams are shared among biologists. Rulesets, needed in the validation process, can be generated for any graphical notation that a developer desires, using either Schematron or Groovy. The plugin also provides support for filtering validation results, validating on a subset of rules, and distinguishing errors and warnings. © Published by Oxford University Press 2011.

WikiPathways (http://www.wikipathways.org) is an open, collaborative platform for capturing and disseminating models of biological pathways for data visualization and analysis. Since our last NAR update, 4 years ago, WikiPathways has experienced massive growth in content, which continues to be contributed by hundreds of individuals each year. New aspects of the diversity and depth of the collected pathways are described from the perspective of researchers interested in using pathway information in their studies. We provide updates on extensions and services to support pathway analysis and visualization via popular standalone tools, i.e. PathVisio and Cytoscape, web applications and common programming environments. We introduce the Quick Edit feature for pathway authors and curators, in addition to new means of publishing pathways and maintaining custom pathway collections to serve specific research topics and communities. In addition to the latest milestones in our pathway collection and curation effort, we also highlight the latest means to access the content as publishable figures, as standard data files, and as linked data, including bulk and programmatic access. © The Author(s) 2015.
