| Abstract | Mobile networking and collaboration of underwater robots is of interest in many applications such as oceanography, environmental monitoring, and underwater surveillance. In this paper, an LED-based underwater optical communication system is designed and implemented for such applications. In contrast with laser-based communication systems, the characteristics of small size and low cost of the LED-based systems are very appealing, especially for small underwater robots. The presented system has a sound balance among desired characteristics of small size (in the order of centimeters), low energy consumption (500 mW on average), and median communication distance (20-30 m, in comparison with several meters available from most similar LED-based systems). The system design is described including the realization of the transmitter and the receiver, as well as the methods for achieving robustness to noise. System performance is experimentally tested in terms of signal strength and waveform shape versus communication distance and transmitting frequency. Experiments on data transmission is conducted to check the bit error rate under different baud rates. The experimental results show that the presented system has a good balance between communication performance and robustness. |

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.
