| Abstract | In dynamic spectrum auction, if a buyer locates in a “critical” place, interfering with many other buyers, its occupancy of the spectrum may deprive many others the transmission opportunity. In this paper, we for the first time propose a location-aware online double auction mechanism, LOTUS. The biggest challenge is: the spectrum requests are sporadic, an interference-harmful buyer may request spectrum earlier than others, making it difficult to decide whether to grant its spectrum request instantly. To address the challenge, we considers the opportunity cost of the spectrum allocation regarding location-based interference conditions. We introduce the “interference discount” to characterize the interference harmfulness. The simulation results show that LOTUS can improve buyers' utility by more than 110% over the static auction, and 25% over the online auction without considering interference discount. The spectrum utilization is enhanced by 120% over static auction, and 65.3% over the online auction without considering interference discount. |

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.
