| Abstract | Placement of relay nodes in a wireless sensor network has been considered throughout the literature. The problem becomes more complex when we consider placing additional nodes into a mobile adhoc network. The mobility of the network requires that relay placement be changed constantly in order to maintain network connectivity, and the calculation of relay co-ordinates must take place using partial (non-global) information due to scalability issues. This paper introduces the concept of performing distributed MANET relay placement within nodes' n-hop neighbourhoods. Networked Autonomous Vehicles (NAVs) act as mobile relays placing themselves at chosen locations. Various algorithms to maintain connectivity are suggested and compared, the most efficient being a bridge and articulation point detection (BAP) algorithm. It is shown that the combined use of up to five additional relay nodes and this algorithm can increase the average ground unit network connectivity by up to 82% and the size of the network's largest segment by up to 54% in mobile adhoc networks of 10 to 25 nodes. |

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.
