| Abstract | In this paper we consider the problem of robotic router formation, where a node needs to maintain its connectivity to a fixed station by using a number of mobile routers. While most literature on this topic optimizes the formation of the routers by maximizing the Fiedler eigenvalue of the resulting graph, we take a different approach and consider the true reception quality. By following a transmission of a bit from the transmitter to the receiver, we formulate the probability of bit error of the reception as a function of the positions of the routers. Then, we formulate an optimization problem that aims at minimizing the probability of bit error in the receiver while considering the environmental constraints. We consider two cases of multihop and diversity, for which we characterize the optimum configuration under certain conditions. We show that the robotic router graph formed by considering the true reception quality may not be the same as the one found by maximizing the Fiedler eigenvalue. Furthermore, only maximizing the Fiedler eigenvalue, without considering the reception quality, can result in a performance loss. |

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.
