| Abstract | The data transmission capacity of wireless sensor networks is known to be limited by both the hardware and the sink-based communication paradigm. In a multi-sink application scenario, simultaneous queries may generate traffic exceeding the transmission capacity of certain sensor nodes. In this paper, we intend to share the capacity of the sensors among multiple sinks by adjusting their query ranges, so that no sensor gets congested and every sink is able to monitor an area with desired data rate. Specifically, the max-min fairness will be ensured. An analytical model is presented and theoretical results for two-sink case is given. Then a distributed algorithm allowing sinks to approach the optimal query range with local knowledge is developed. Finally, simulation results are shown to illustrate the characteristics of this capacity sharing problem and to validate the effectiveness of our distributed algorithm. |

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.
