| Abstract | The problem of efficient message delivery to multiple nodes has been widely studied for ad-hoc networks, be it sensor or mobile ad-hoc networks (MANETs). We are concerned with deterministic delivery guarantees, i.e. the delivery ratio for any given message is guaranteed not to fall below a threshold specified for that message. This threshold can be considered to take the special case value of 100% when message delivery is guaranteed to all nodes. Guaranteeing delivery to all in a group, however desirable, often involves making a simplifying assumption that no destination node leaves the group nor crashes during an execution of the protocol. However, the nodes that make up an ad-hoc network are prone to failures and are likely to leave the group, something which undermines the validity of the assumption. We outline a protocol, called Scribble, which permits the minimum threshold to be less than 100%, thus allowing a few nodes to depart or crash during the execution. More precisely, it provides what we call k-deterministic delivery guarantees, where delivery is guaranteed to at least k destination nodes. The value of k is chosen by the application is required to be a realistic value. Such a service is called manycast. |

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.
