| Abstract | In this paper we propose a push-relabel algorithm to solve the Max-Flow Problem (MFP) in location-aware wireless sensor networks (WSNs). This algorithm is based on the push-relabel method and uses the location of nodes and their radio ranges to make an initial gradient in the network by assigning initial values to the height of the nodes. We prove the correctness of the algorithm which finds max-flow in $O(n^{2})$ time and $O(n^{2}$ m) message complexities, in which n and m are the number of nodes and links respectively. Furthermore, a self-stabilizing version of the algorithm has been proposed which adapts the max-flow to the network changes. Simulation results show that this algorithm improves existing distributed algorithms significantly and reduces the number of control messages around 32% in compare with generic push-relabel 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.
