| Abstract | The objective of this paper is to find numerical upper bounds on the optimal solution to the sensor placement problem. Given noisy measurements and knowledge of the state correlation matrix, the sensor placement problem can be formulated as an integer programming problem using a linear minimum mean squared error estimator. Since finding the optimal placements of a fixed number of sensors in a large network is computationally infeasible, finding bounds for the optimal solution is a fundamental task. In this paper we present a family of nested bounds using matrix pencils and their generalized eigenvalues that upper bound the optimal performance. In the analysis we consider nodes that we want to place sensors and other nodes where we cannot or do not want to place sensors. Finally we compare the upper bounds with the optimal solution using simulations on a 5 by 5 grid network. |

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.
