| Abstract | Reliably collecting data from mobile sensor nodes is essential with the increasing popularity of integrating mobile nodes into stationary sensor network infrastructure for various scientific and social applications. Existing sensor data collection protocols demonstrate high reliability in stationary sensor networks, but when applied to mobile nodes, the packet acceptance ratio drops significantly. This is because the topology changes due to mobility are not well detected by routing protocols. We present Location-Aware Relay Association Protocol (LRP), a relay association protocol that is independent of any routing protocols and adopts distance measurement techniques to detect topology changes. Instead of reinventing yet another routing protocol, LRP complements it by estimating the distances between a mobile node and its current parent node in the infrastructure network. LRP notifies the routing protocol to trigger route refreshes when a node moves out of the effective communication range of its parent. By continuously adapting to changing topologies in a fast and efficient manner, LRP improves the network reliability and throughput when nodes are moving. In test bed experiments, LRP achieves higher network throughput and lower control overhead than other comparable protocol in data collection applications with high data rate under various mobile environments. |

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.
