Abstract | The security of the messages travelling in ad hoc networks is one of the most critical issues of creating and maintaining practical networks over a period of time. Being a multi-hop network, the behaviour of the nodes forwarding the message becomes critical, and thus it is useful to have a certain level of trust on the forwarding nodes. The trust value, however, does not remain stable and must change with time, as a friendly node may turn malicious, and vice versa. Moreover, it is also desirable that the message contents are not easily revealed to the intermediate nodes and there is even some protection against message modification. However, the encryption and message integrity checking comes at a price of increased computation overheard at multiple nodes. This work introduces an approach that can be applied to calculate the trust in a dynamic way, and also protect the message against modification, without significantly increasing the overheads. The performance of the proposed approach has been established through simulations in terms of packet delivery ratio and the number of times the packet was broken into parts, and the results of the simulation were found to support he above claim. |

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.
