| Abstract | Many multicast routing protocols has proposed to support efficient multimedia application, PIM-SM and CBT protocols remain the most used multicast routing protocol; they propose using a Shared Tree ST to forward multicast packets. The prime problem concerning ST construction is to determine an optimal multicast router in the network as root; this problem is called Core selection. This problem influences the multicast routing tree structure, and therefore influences performances of the multicast session and multicast routing scheme. Determination of a best core position is an NP complete problem, first proposed by Wall, which needs to be solved with a heuristic algorithm. In this paper we propose a new Core selection algorithm based on Parallel GRAS Procedure and new CMP fitness function. 2DV-PGRASP-CR selects Core by considering cost, delay and delay variation functions and can be easily integrated to bootstrap RP protocol used by PIM-SM and CBT. Simulation results show that good performance is achieved in multicast cost. |

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.
