| Abstract | In terrestrial wireless networks, station (STA) adopts virtual carrier sensing mechanism to avoid hidden terminal problem. The neighbors which had received RTS/CTS will set a Network Allocation Vector (NAV) and suspend the transmission in NAV duration to avoid data collision. Due to the impacts of low data rate and long propagation delay, setting NAV duration in the underwater acoustic networks (UANs) is much difficult than that in the terrestrial wireless networks. A too short NAV duration such that the transmission data to be collided. A too long NAV duration leads the low bandwidth utilization such that low network throughput. In this paper, a stair-like NAV duration setting mechanism is proposed to set a precisely NAV duration on each STA. The proposed stair-like NAV duration setting can overcome the long propagation delay in UANs and minimize the suspended transmission time. Therefore, the stair-like NAV setting mechanism can enhance the network through and avoid the data to be collided. |

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.
