| Abstract | Social cloud systems, which aggregate the computing capabilities of a large pool of users, have emerged in recent years as a key solution for resource provision and sharing in large-scale online communities due to their inherent flexibility and cost-effectiveness. However, the performance and reliability of these systems depend on the users' cooperative behavior in sharing their computing capabilities. Hence, incentive mechanisms are needed to deter users from free-riding. In this paper, we first model the selfish behavior of the users supplying resources and aiming to maximize their own benefits, and compute the performance of the resulting non-cooperative equilibrium, which is highly inefficient. We then augment the existing job allocation schemes currently implemented in social cloud systems with a novel class of incentive mechanisms based on reputation-based pricing and collective punishment schemes that compel suppliers to change their selfish strategies in a manner that improves the efficiency of the system. We study the cloud system operator's problem of jointly optimizing the incentive mechanism and the job allocation scheme in order to find an optimal social cloud protocol which eliminates the free-riding behavior of suppliers while maximizing the social welfare of the system. We rigorously prove that, using only simple designs for both the incentive mechanism and the job allocation scheme, the resulting protocol provides significant improvements in terms of the social welfare compared to existing social cloud systems. |

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.
