| Abstract | Using unlicensed spectrums is a key factor in popularity of WLANs. Meanwhile, the interference is becoming severer in coming time because of network expansion. Assigning channels for AP in distributed way only reduce interference around single AP rather than reducing system interference. However systematic optimizations usually require real-time information which increase complexity for applying. This paper identifies a idea for optimizing system interference from the view of several sub-areas. Actually, interferences spread regionally depending on signal propagation. Conflict-areas are divided according to the interfering range. We define an index to present interference in conflict-areas and the goal is to minimize maximum index of the areas. It means that interferences of the whole network are comparatively low and distributed evenly. Both the theoretical evaluation and experiments in real network show that the conflict-area method is reasonable. Average interferences in most conflict-areas under experiments are reduced (about 50%) or remain unchanged (about 40%). |

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.
