| Abstract | Although request-to-send clear-to-send (RTS-CTS) has been introduced as a uniform improvement over carrier sense multiple access (CSMA) in a wireless LAN environment, it is not. As it tries to solve the hidden-stations problem of CSMA, it creates new problems derived from the interaction among its control and data packets. We systematically identify and classify the sequences of events where CSMA and RTS-CTS depart from an ideal behavior, and we define a reference configuration and an analytical model on the basis of which a comparative study of protocol performance is made. The results show that RTS-CTS falls short of an ideal protocol, in some cases performing even worse than CSMA. This is especially noticeable in situations where the interaction between control packets in RTS-CTS prevents transmissions that under CSMA could occur concurrently and successfully. |

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.
