| Abstract | Time synchronization is a critical middleware service of distributed system. In particular, wireless sensor networks is a distributed system which makes extensive use of synchronized time in many contexts (e.g. for data fusion, TDMA schedules, synchronized sleep periods, etc.). In addition, synchronization precision has become a critical area of research today. Time synchronization with very high precision is needed at some special application. In this paper, we proposed a high degree of accuracy time synchronization Protocol--Physical Layer Integrated Synchronization Protocol (PLISP). Different from adding timestamp in MAC layer of traditional time synchronization protocol, we advocate a novel way to add timestamp. We add timestamp in physical layer which can utmost reduce influence of nondeterminacy factor to synchronization precision. We get time synchronization precision is less than 1 µs in experiments. Result shows that this method is feasible and can be used to wireless sensor networks. |

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.
