| Abstract | The coverage problem in which a set of sensors is required to collaborate so as to preserve the whole perimeter of a big object is known as the perimeter coverage problem. With the assumption that two sensors are neighbors and connected if they have overlapping cover ranges, we have developed distributed algorithms to find the set of sensors to cover the entire perimeter with the minimum size and the minimum cost previously. Unfortunately, this assumption is invalid when some security measures, such as a secret key management scheme, are applied to the sensors. In this paper, we are specifically interested in finding a set of sensors to monitor the target object with the minimum size and the minimum cost. At the same time, the sensors inside the set can communicate with its secure neighbors such that a secure communication path can be formed from any sensor inside the set to another sensor inside the same set. We first demonstrate why our previously proposed algorithms fail under this situation and further propose a modified model and algorithm so that the minimum size and minimum cost sets of sensors can be found. Finally, we simulate our proposed algorithm to demonstrate its effectiveness. |

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.
