| Abstract | This paper presents a distributed adaptive QoS medium access control (DAQ-MAC) protocol for mobile ad hoc networks. The protocol assigns nodes accessing channel in three phases: the prioritization phase, the contention phase and the transmission phase. The prioritizations of data packets are expressed by a few binary signed digits. In the prioritization phase, when binary signed digit is “0”, nodes sense the channel by a Tslot, while binary signed digit is “1”, nodes send a forecast bursts (FB). Therefore, every node can differentiate the priorities by sending FB and sensing the channel. Thus only the nodes with higher priority packets can access in the contention phase. In the contention phase, only one node can access in the channel successfully without collisions by collision resolution algorithm. Simulation results show that with the number of the node increasing, the performance of the DAQ-MAC protocol is better than the HIPERLAN Type 1 (HIgh Performance Radio Local Area Networks) protocol in terms of throughput, average packets discard rate and average packet delay. |

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.
