|Abstract||The Network-on-Chip (NoC) paradigm has emerged as a scalable interconnection infrastructure for modern multicore chips. However, with growing levels of integration, the traditional NoCs suffer from high latency and energy dissipation in on-chip data transfer due to conventional multihop metal/dielectric-based interconnects. Three-dimensional integration, on-chip photonics, RF, and wireless links have been proposed as radical low-power and low-latency alternatives to the conventional planar wire-based designs. Wireless NoCs with Carbon NanoTube (CNT) antennas are shown to outperform traditional wire-based NoCs significantly in achievable data rate and energy dissipation. However, such emerging and transformative technologies will be prone to high levels of failures due to various issues related to manufacturing challenges and integration. On the other hand, several naturally occurring complex networks such as colonies of microbes and the World Wide Web are known to be inherently robust against high rates of failures and harsh environments. This article advocates adoption of such complex network-based architectures to minimize the effect of wireless link failures on the performance of the NoC. Through cycle-accurate simulations it is shown that the wireless NoC architectures inspired by natural complex networks perform better than their conventional wired counterparts even in the presence of high degrees of link failures. We demonstrate the robustness of the proposed wireless NoC architecture by incorporating both uniform and application-specific traffic patterns.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
