| Abstract | Traffic accidents and congestion are the most common on-road problems that might be anywhere and anytime. Recently, to deal with such problems, well-coordinated wireless communication system between vehicles, road side units (RSU), drones, etc., namely vehicle-to-everything (V2X) communication system, has been considered as a key technology enabling on-road human safety and convenience. One of the well-known building blocks of the V2X communication system is Wi-Fi based Dedicated Short Range Communication (DSRC) which performs stably, owing to a long year of study, simplicity and capability of distributed operation. In spite of promising opportunities brought by DSRC, its elaborate performance evaluation must be done under real-world scenarios, in advance to the actual use, since its performance is directly related to human and vehicle safety. In this context, this article presents field test results of DSRC-based V2X communication system we implemented. As a result of the line-of-sight (LoS) test, the distance represented by 90% or more of packet reception rate (PRR) was 720 meters at 5 dBm, and 1,035 meters at 11 dBm. In Non-LoS (NLOS) shadowing test, the distance represented by 90% or more of PRR was 175 meters at 5 dBm, and 520 meters at 11 dBm. And in NLoS intersection test, the distance represented by 90% or more of PRR was 320 meters at 5 dBm, and 515 meters at 11 dBm. Meanwhile, the distance for PRR 90% was up to 520 meters at urban environment, 1,219 meters on highway, and 1,700 meters inside a tunnel. |

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.
