| Abstract | WiMedia UWB platform consists of two specifications; WiMedia MAC and PHY. WiMedia MAC may give support to allow industry protocol applications to share UWB resource. Actually, in addition to certified wireless USB, wireless 1394 and TCP/IP, many other industry protocols can reside on top of the WiMedia UWB platform. Thus the mechanism to decide medium access time between them is very important to support QoS. However current WiMedia MAC only defines differentiated medium access idle time via Access Categories(ACs) for traffic data type. The medium access idle time by the ACs may not guarantee QoS for multiple industry protocol applications. For example, if two industry protocols, wireless USB and wireless 1394, use the same AC by same traffic data type, the protocols may easily have contention collision due to same idle time through same AC, because ACs decide medium idle time. Within WiMedia MAC specification, all application devices shall wait for specific idle time called Arbitration Interframe Space(AIFS), which is defined by ACs and PCA parameters, before accessing the shared medium. After AIFS duration, devices can transmit data on the shared medium. Since same AC has the same AIFS Duration, in the multiple industry protocol environments, an idle time via the ACs may be very inadequate for a medium access QoS. In this paper, we concentrate on defining an industry protocol-based AIFS parameter for a new medium access method. The values of industry protocol-based AIFS parameters are determined by priority of industry protocol applications. End user can set the priority of an industry protocol for its own use case. |

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.
