| Abstract | Sparse wireless sensor networks are characterized by the distances the sensors are from each other. In this type of network, gathering data from all sensors in a point of interest might be a difficult task, and in many cases a mobile robot is used to travel along the sensors and collect data from them. In this case, we need to provide the robot with a route that minimizes the traveled distance and allows data collection from all sensors. This problem can be modeled as the classic Traveling Salesman Problem (TSP). However, when the sensors have an influence area bounded by a circle, for example, it is not necessary that the robot touches each sensor, but only a point inside the covered area. In this case, the problem can be modeled as a special case TSP with Neighborhoods (TSPN). This work presents a new approach based on continuous Ant Colony Optimization (ACO) and simple combinatorial technique for TSP in 0order to solve that special case of TSPN. The experiments performed indicate that significant improvements are obtained with the proposed heuristic when compared with other methods found in literature. |

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.
