| Abstract | With the anticipation of Positive Train Control (PTC), as well as many other advanced rail applications, a modern end-to-end communication network infrastructure has become an essential requirement for the North American railroad industry. One focus area is on wireless technologies for track-side and yard deployments. Among the available broadband technologies, Mobile WiMAX has emerged as the most favorable solution for deployment in such an environment. It provides high throughput, large coverage and the support for many diverse applications, with attractive features like seamless handover, Quality-of-Service (QoS), the recovery from packet loss through mechanisms like Hybrid-Automatic Repeat reQuest (H-ARQ) and vehicular mobility support. In this paper, we provide an overview of our research endeavors in evaluating Mobile WiMAX. We discuss our design and implementation of Mobile WiMAX computer model based on Network Simulator 2 (NS-2), which can simulate sophisticated scenarios frequently encountered by the railcars. We describe our experience in setting up our WiMAX testbeds in Ashland, NE and Logan, IA, utilizing the infrastructure from BNSF and UP in those locations, respectively. Since our test beds serve as prototypes, similar design principles can be applied for the eventual large-scale nationwide network deployment by the railroad industry. Furthermore, we present laboratory and field test results that clearly validate our design principles and demonstrates the advantages of Mobile WiMAX deployments for railroad operations. |

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.
