| Abstract | Mobile social network (MSN) has been widely studied as a novel and effective way for communication in the current era of fast developing mobile devices, which enables the contents and services to be delivered opportunistically when mobile users contact. In this paper, we aim to optimize the content delivery from the content provider (CP) to the subscribers via relays in between. Tandem queueing model is applied to model the content delivery process, based on which absorbing Markov chain is used to derive the quality of the content delivery service received by the subscribers. The validity of the proposed queuing model has been verified by our simulation results. Observing that the content provider always has dominant control on the content delivery process and is pursuing the maximum profit by strategically designing the “rights” and “obligation” items for the subscribers, contract theory is adopted to reach an economically optimal solution. The numerical results verify the effectiveness of the contract-theoretic approach in maximizing the content provider's profit, and the capability to ensure the satisfaction of the heterogeneous subscribers with different quality of service (QoS) requirements. |

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.
