| Abstract | Since there is no fixed infrastructure or centralized management in Wireless Sensors Networks (WSNs), a connected Dominating Set (CDS) has been proposed as the virtual backbone. The CDS play a major role in routing, broadcasting, coverage and activity scheduling. To reduce the traffic during communication and prolong network lifetime, it is desirable to construct a Minimum CDS (MCDS). Self-stabilization is a theoretical framework of non-masking fault tolerant distributed algorithms. A self stabilizing system tolerates any kind and any finite number of transient faults, such as power termination, message loss, memory corruption, and topology change. There are few publications dealing with Self-Stabilizing MCDS (SSMCDS) where all of them, the network has been modeled in Unit Disk Graph (UDG), in which each node has the same transmission range. In real world this kind of networks are not necessarily contain nodes with similar transmission range. As a new approach, network has been modeled by Disk Graph with Bidirectional links (DGB), in which nodes have different transmission range. In this paper has presented a new distributed approximation algorithm for SS-MCDS problem in DGB (called SS-MCDS-DGB) with constant approximation ratio and $O(n^{2})$ time complexity using unfair central daemon. |

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.
