| Abstract | Different from terrestrial sensor networks, underwater sensor networks use acoustic channels for communication and most sensor nodes are mobile due to water current. These distinctions feature underwater sensor networks with highly dynamic topology, high bit error rate, large propagation delay, and low available bandwidth. Traditional ARQ series are not suitable due to their frequent feedbacks, which is undesirable in underwater environment. On the other hand, pure FEC can't apply into underwater sensor networks, not only because of its complexity, but also because it needs some feedbacks. This paper studied transport protocol in underwater sensor networks, implemented a reliable lightweight RFEC-based encoding and decoding algorithm. Then combine the algorithm with ARQ to a transport protocol. In this way, take advantages of FEC to deal with high bit error, and ARQ to avoid feedbacks. Through simulation experiment on method of random sequences generation, parameters selection, and transmission strategy, some useful conclusion is gotten. It provides practical data and references on practical application of underwater sensor networks. |

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.
