| Abstract | ALLIANCES is a cooperative random access protocol proposed for taking advantage of diversity and resolving collisions in wireless networks. A multicluster extension of ALLIANCES was also proposed that enables its application to a large-scale wireless sensor network (WSN). In this paper, we propose a dominating set based approach coupled with destination-based routing to solve the problem in a large-scale WSN without the need of a clustering protocol. The approach is based on the concept of dominating set in graph theory. A subset of vertices of a graph is a dominating set if every vertex not in the subset is adjacent to at least one of the vertex in the subset. The nodes will transmit to only one of its dominating neighbors based on the packets destination. A particular (dominating or non-dominating) node can have more than one dominating neighbor, and the transmitted next hop will always be a dominating node based on the destination. We have shown that this approach can achieve a better performance in terms of throughput (successfully transmitted packets per timeslot) and delay. Also, there are evidences that in an ad-hoc network, the dominating set based approach can yield more stability to the network (in terms of lifetime of nodes) than the clustering approach. So, overall, in an ad-hoc network, we expect much better performance by adopting dominating set based approach to ALLIANCES. |

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.
