| Abstract | In a multi-hop wireless network, each node has a transmission radius and is able to send a message to one or all of its neighbors that are located within the radius. In a broadcasting task, a source node sends the same message to all the nodes in the network. Some existing solutions apply re-broadcasting from each cluster-head or border node in a clustered structure. We propose to reduce the communication overhead of the broadcasting algorithm by applying the concept of internal nodes. The maintenance of internal nodes requires much less communication overhead than the maintenance of the cluster structure of the nodes. In one-to-all broadcasting, only the internal nodes forward the message, while in the one-to-one case, messages are forwarded on the edges that connect two internal nodes and on edges that connect each non-internal node with its closest internal node. Existing notions of internal nodes are improved by using node degrees instead of their IDs in internal node decisions. Highest node degrees are also proposed for reducing the number of cluster-heads and border nodes in a clustering algorithm. Further savings are obtained if GPS and the concept of planar subgraphs are used for one-to-one networks. In case of one-to-all model, no re-broadcasting is needed if all neighbors have already received the message. The important features of the proposed algorithms are their reliability, significant savings in the re-broadcasting, and their localized and parameterless behavior. The reduction in the communication overhead for the broadcasting task, with respect to existing methods, is measured experimentally. |

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.
