Abstract | Wireless sensor networks is one of important information acquisition methods and also has been a promising technique for many applications in recent years. Node localization is one of challenging and fundamental topics in distributed WSNs research. The goal of this paper is to propose an efficient range-free localization algorithm in WSN. We use directional antennas other than omnidirectional antennas. While the mobile beacon node using several directional antennas moves, it periodically broadcasts its packet in K directions. Ordinary sensor nodes are able to estimate their position based on the messages received from only one virtual beacon. We also use discrete imprecision range measurement. It can send messages in different lever of power to obtain the approximate distance between neighbor nodes. Considering WSN is an event-based network, we propose a refinement phase in latter part of this paper. The main advantage of the algorithm is that it is both simple and economical. Our simulation has shown that the given approach is able to provide accurate and robust estimation of sensor location. |

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.
