| Abstract | The Cognitive Network Management System (CNMS) is a joint research initiative between Rockwell Collins and the Institute for Human Machine Cognition that aims to provide automated, policy-based real time network management for complex MANET networks. CNMS is a lightweight and efficient policy management framework designed to mitigate the need for centralized network management, reduce operator hands-on time, and increase network reliability. CNMS provides the necessary reasoning and enforcement mechanisms for the on-demand management of network topology and communication resources. Furthermore, it supports fully distributed policy learning mechanisms that enable networked devices to adapt at run-time to unanticipated network conditions and application requirements by creating and distributing learned policies. In this paper we describe the CNMS architecture and functionality. We focus our discussions on the CNMS architecture and policy learning mechanisms. Policy learning in CNMS is intrinsically distributed, and based on network performance observations for the refinement of contexts, and actions. In this paper we describe two examples for policy adaptation, one based on link capacity monitoring, and one based on adaptive frequency hoping strategies for interference mitigation. We then present some results from NS-3 evaluations of these two examples. CNMS has been implemented and tested in a two channel wireless testbed using the Universal Software Radio Peripheral (USRP) [1] and 802.11 wireless networking communication. We briefly discuss the testbed and describe some of our experimental results followed by a brief discussion of our findings, and recommendations for future work. |

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.
