| Abstract | Mobile ad-hoc networks (MANET) has highly dynamic topology, open access of wireless channel and unpredictable behaviors; however, absence of effective security mechanism render MANET more vulnerable to positive attacks. Conventional assessments always require large sample data satisfy specific distribution and establish models through subjective recognition, thus lack common applicability, objectivity and reliability. To solve this problem and make accurate assessment, we propose RAPCA-PP model on basis of Projection Pursuit theory to realize both risk assessment and attributes analysis. Due to Projection Pursuit's theoretical merits, RAPCA-PP is thoroughly data-driven; it can be applied to conditions with small sample quantity, incomplete data and no-prior experience. Using RAGA for solution, RAPCA-PP shows well convergence. Compared with Grey Relations Projection, it demonstrates both better accuracy and higher discrimination. Moreover, our model can analysis attributes by importance and eliminate redundancy. Experiment shows that assessment with eliminated attributes can also correctly reflect each node's performance. RAPCA-PP proved to be suitable for real MANET working scenarios. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
