| Abstract | In legacy networks, overlay multicast protocols are stateless multicast relying on unicast with IP addresses regarding multicast routing states on routers, and thus they offer cost-effectiveness and robustness. Wireless sensor networks (WSNs) consist of a large number of randomly deployed sensors with unattended batteries and constrained device capabilities. For non-uniform and resource-sensitive WSNs multicast protocols also have taken an overlay approach. The protocols establish a cost-optimal structure, a Steiner tree, among destinations as an overlay structure and exploit geographic routing for unicasting. However, such concentration on the Steiner tree structure may paradoxically burden the irregular and resource-constrained WSNs with heavy loads for heuristic structure construction and fault-tolerant maintenance. In addition, it leads to frequent tree reconstruction, thus it could harm data multicast transmission seriously. Regarding these problems, we consider a proxy district per a destination for overlay tree formation to prevent structural dynamic alteration and support local state management. This district-based overlay multicast might be able to keep the stateless advantages of traditional overlay multicast. By overhead analysis and various computational simulations, we prove that our proposal provides robust and efficient multicast transmission. |

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.
