| Abstract | Distributed, self-organized and infrastructure-independent nature of MANET makes it vulnerable to various kinds of attacks. Among them, a threat caused by black hole attack is more prominent. A trust management scheme is a common way to detect and isolate the compromised nodes while a cryptography mechanism shows a failure facing to inner attacks. The previous work proposed two simple models along with trust computation methods to filter out black hole nodes using the benevolent ones and achieved better performance against pure black hole attacks. In this study, a method to prevent gray hole attack, one kind of black hole attack, which is more cunning and clandestine attack is proposed. The neighbour observing model based on watchdog concept is focused on the direct trust value (DTV) to detect single black hole attack. Historical evidence is also taken into consideration against gray hole attacks. Moreover, the neighbour recommendation model that companied with indirect trust value (ITV) is used to detect the cooperative black hole attacks. On the other hand, the proposed method tries to balance the trust values from different neighbour nodes to mitigate the damage by their deceiving. The simulation results demonstrate the advantages of proposed method by punishing malicious actions to prevent the camouflage and deception in the attack. |

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.
