| Abstract | WiMedia MAC protocol supports fully distributed data communications in high data rate wireless personal area networks (WPANs). WiMedia MAC includes a distributed reservation protocol (DRP) for synchronous traffic and a prioritized contention access (PCA) protocol for asynchronous traffic. Since PCA is based on the carrier-sense multiple access with collision avoidance (CSMA/CA) mechanism, it suffers from low throughput due to collision, especially when the number of devices is large. In this paper, we propose a novel channel access scheme called deterministic channel access (DCA), which determines the transmission order among devices by means of beacon frames. Since all devices follow the deterministic transmission order, collision-free channel access can be achieved and thus the throughput can be significantly improved. Extensive simulation results demonstrate that DCA outperforms PCA in terms of throughput under different situations. |

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.
