| Abstract | In recent years, direct data transfer between mobile devices has attracted significant interest from the research community. In this paper, we focus on the scenario in which a group of clients need to exchange a set of files over a lossless broadcast channel. Initially, each client has a subset of files available to it as a side information and needs to obtain the some of the other files in the set. The clients employ the network coding technique to increase efficiency. We assume that each client is selfish, i.e., its goal is to minimize its own transmission rate while trying to receive as much information as possible from other clients. The process is mediated by a one of the clients, referred to as a broker, that obtains clients' bids and determines their transmissions rates. Our goal is to design a truthful mechanism that provides incentives for the clients to report the true values of the requested packets. While mechanisms based on the Vickery-Clarke-Groves (VCG) auction are known to be truthful, they involve monetary transactions, and hence are not suitable for the problem at hand. Accordingly, we propose a simple non-monetary algorithm that guarantees truthfulness. Our analytical results and a numerical study indicate that the total utility of all clients under our algorithm is very close to the optimum. |

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.
