Abstract | Use of multiple frequency channels in a wireless sensor network alleviates bandwidth limitations in communication. Moreover, operating wireless sensor network with low duty-cycle conserves energy and thus prolongs network lifetime. With the benefits, these approaches bring challenges for data dissemination. In data dissemination each node tries to forward data to maximum neighbors in order to achieve maximum network coverage. It becomes difficult for each node to make forwarding decisions in a context where multiple channels are available with different channel conditions and many of its neighbors are sleeping due to low duty-cycle. Hence, selection of the right channel is a critical issue for each node to disseminate data reliably and efficiently. In this paper, we present a distributed channel selection scheme for efficient data dissemination in low duty-cycle multi-channel multi-hop wireless sensor network and name it as a Smart Channel Selection Scheme. Through simulations, we have analyzed the performance of our proposed approach and compared it with three relevant approaches i.e. Random Channel Selection, Channels' Condition based Channel Selection, and Neighbors based Channel Selection. Simulation results confirm that our approach outperforms the relevant approaches in terms of reliable and efficient data dissemination. With proposed Smart Channel Selection Scheme we can achieve more than 70% packet delivery ratio under as low as 40% duty-cycle. |

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.
