| Abstract | Traditional ad hoc wireless networks designed for best effort performance lack provisions to maintain network connectivity, particularly if nodes are mobile. For applications that require continual and timely service, current commercial grade ad hoc wireless networks cannot satisfy these demands. We study several architecture options that proactively deploy additional fixed or mobile infrastructure nodes (we call helper nodes) to help maintain user network connectivity. Our goal is to answer the questions of when and how helper nodes should be used. Using random line networks as a point of departure, we compare random and strategic helper node deployment schemes and show that at a nominal normalized user node density of N ~ 1, the number of helper nodes needed under random helper deployment can be more than 10 times the number needed under strategic deployment. At lower TV, this factor increases significantly without bound. Based on the expected number of helper nodes needed for different values of N, we delineate scenarios where each scheme is a sensible architecture choice. |

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.
