| Abstract | We present a distributed algorithm for the navigation of an Unmanned Ground Vehicle (UGV) towards a set of identified target nodes in coordinate-free and localization-free wireless sensor and actuator networks. The navigation algorithm proceeds in two phases: first, a node level is determined based on a hop distance from the target nodes, which is accomplished by the network nodes without the need for any UGV action; and second, the UGV uses potential fields created by the network actuators to move towards the target nodes, requiring cooperation between certain actuator nodes and the UGV. The hop distance to the target nodes is used to control the main moving direction while the potential field, which can be measured by listeners on the UGV, is used to determine the UGV's movement. The major contribution of this paper is that the algorithm is fully distributed compared to the existing results in the field, which is suitable for real-time implementation. Meanwhile, the presenting algorithm uses three actuators to generate a potential field, which makes the algorithm more robust and flexible. A study on the communication complexity of the algorithm is presented as well as simulation examples that verify the presented algorithm. |

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.
