| Abstract | This paper presents performance of call admission control and resource reservation schemes in WCDMA cellular systems that has been developed based on assumptions more realistic than existing proposals. In order to guarantee the handoff dropping probability, the mobility of the user is predicted based on the mobility history of users. The mobility prediction scheme used in this work is based on computational learning theory, which has shown that prediction is synonymous with data compression. In order to utilize resource more efficiently, we predict not only the cell to which the mobile will handoff but also when the handoff will occur. Based on the mobility prediction, resource is reserved in terms of signal to interference ratio guard margin (SIRGM) to guarantee some target handoff dropping probability. The admission threshold is adaptively controlled to achieve a better balance between guaranteeing handoff dropping probability and maximizing resource utilization. Simulation results show that the mobility based resource reservation scheme outperforms the static-reservation scheme |

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.
