| Abstract | We present a distributed scheduling algorithm for provisioning of guaranteed link bandwidths in ad hoc mesh networks. The guaranteed link bandwidths are necessary to provide deterministic end-to-end bandwidth guarantees. Using Time Division Multiple Access (TDMA), links are assigned slots in each frame and during each slot a number of non-conflicting links can transmit simultaneously. The bandwidth of each link is given by the number of slots assigned to it the frame and the modulation used in the slots. Our scheduling algorithm has two parts. The first part of the algorithm is an iterative procedure that finds locally feasible schedules by exchanging link scheduling information between nodes. The iterative procedure is based on the distributed Bellman-Ford algorithm running on the conflict graph, whose partial view is available at every node. The second part of the algorithm is a wave based termination procedure used to detect when all nodes are locally scheduled and a new schedule should be activated. We use analysis to show the worst case convergence time of the algorithm and simulations to show performance of the algorithm in practice. |

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.
