| Abstract | As a potentially competitive technique, erasure coding has been employed in wireless sensor networks (WSNs) to enhance transmission reliability. In this paper, to design a practical and efficient redundancy mechanism in WSNs, we firstly provide a theoretical study of packet delivery probability and average energy consumption for retransmission and redundancy mechanisms. The theoretical results indicate that in WSNs, the adaptive redundancy coding mechanism is more energy efficient than retransmission while keeping the same level of reliability in most scenarios. Then based on the mapping table and two basic design principles obtained from the theoretical analysis, we propose a reliable transport protocol ARRTP which combines the adaptive redundancy mechanism and partial retransmission. The simulation and trace-driven results both verify that when the loss probability varies from low to high, our protocol provides reliability with comparably lower energy consumption. Furthermore, compared with fixed redundancy degrees, the robustness of the adaptive mechanism are also evaluated. |

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.
