| Abstract | Data packets in multi-hop wireless sensor networks require a variety of Communication Reliability (CR) according to applications. Recently, a scheme for supporting a desired CR, called AC, has proposed. In order to support the desired CR, AC simply maintains 100% of data packets of a source at intermediate nodes on a routing path which do not satisfy the desired CR. However, since AC does not consider the link quality of each intermediate node on the routing path, it highly increases the number of total packets which are transmitted on the routing path for achieving the desired CR. To solve the high number of totally transmitted packets in AC, we propose an effective transmission scheme, MTTP, which can reduce the number of totally transmitted packets for achieving the desired CR. By geometric programming, MTTP allocates an optimized one-hop packet transmission rate of each wireless link by considering the quality of wireless links on the routing path. However, AC and MTTP consider only one next-hop node on the routing path even though one node has many one-hop neighbors in practice. Accordingly, we propose another scheme, MTTP_Prime, which consider many one-hop neighbors. By dynamic programming, MTTP_Prime selects a routing path with optimized one-hop packet transmission rates in terms of the number of totally transmitted packets. Simulation results verify that MTTP is superior to AC, and MTTP_Prime is superior to MTTP. |

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.
