| Abstract | The ability to correctly determine their neighborhood is a fundamental requirement for nodes in ad hoc and sensor networks. Many applications, protocols, and system functionality rely on neighborhood discovery. Malicious nodes that taint neighborhood information using wormholes can significantly disrupt the operation of ad hoc networks. Protocols that depend only on cryptographic techniques (e.g, authentication and encryption) may not be able to detect or prevent such attacks. In this paper we propose SECUND, a protocol for creating a SECUre NeighborhooD, that makes use of discrepancies in routing hop count information to detect ¿true¿ neighbors and remove those links to nodes that appear to be neighbors, but are really not neighbors. SECUND is simple, localized and needs no special hardware, localization, or synchronization. We present approaches to improve the efficiency of the process. We evaluate SECUND using simulations and we demonstrate its effectiveness in the presence of multiple and multi-ended wormholes. |

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.
