| Abstract | Wireless Sensor Networks (WSNs) are made of spatially distributed autonomous sensors, which cooperate to monitor a certain physical or environmental condition and pass their data through a network to a central data sink. A promising field of application of WSNs is planet exploration, in which a continuous monitoring of the surface is necessary, to have a clear notion of planet conditions and prepare for a future manned mission. The potentially large size of the region to be monitored and the line-of-sight limitations on remote planets (for instance the Moon, as studied in the SWIPE project [1]), impose constraints on the possibility to have 1-hop sensor-sink communication. Therefore, the sensors must be able to create and maintain a multi-hop ad hoc network, to allow sensed data to reach the sink. This paper extends the Q-Routing algorithm, designed for fixed and mobile networks, in order to be applicable in WSNs. The proposed routing algorithm aims at optimizing the network lifetime, by balancing the routing effort among the sensors, taking into account their current residual batteries, while minimizing the control overhead. Simulation results show an increase of performances, in grid-based networks, which are common topologies for WSNs. |

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.
