| Abstract | Wireless mesh networks are increasingly incorporated into systems recognized as critical infrastructure, including hospitals and smart electrical grids. The Killer Bee exploitation framework is a package of open source tools used to locate, analyze, and disrupt IEEE 802.15.4 low rate networks in these critical systems. Penetration testers use the tool named zbfind to rapidly locate wireless transmitters, estimating distance from received signal strength. Recent work demonstrates that the transmitter distance estimation model in the initial zbfind release is highly inaccurate. Results herein strongly suggest that the Atmel RZUSB stick is a viable hardware platform for zbfind war walking, but that CC2420-based boards are inadequate. This work also demonstrates improved distance estimation models for locating transmitters in hospitals and in smart utility meters while on foot (i.e., War walking). A distance estimation model fitted to data collected in a military hospital is shown to also improve accuracy against an operational ZigBee mesh network in a civilian hospital. Outdoor war walking necessitates different model parameters than used indoors, so this work also demonstrates a distance estimation model for use against smart utility meters. |

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.
