Abstract | Wireless sensor networks are a challenging research field for the telecommunication engineer. The limited resources of the individual sensor nodes impose a redesign of the traditional wireless network protocols. These new designs aim primarily at reducing energy consumption and increasing scalability. Several gradient based routing protocols have been proposed in literature. They construct a cost field towards the sink to be able to forward data along the steepest gradient. A naive way to set up the cost field is flooding. In this paper we present an alternative approach based on received signal strength measurements and timers. The field is constructed in "consecutive waves" emanating from the initializing sink node. The considered cost is a combined metric which takes into account the minimum hop distance to the sink. A simulation study, using the OMNET++ network simulator environment, shows the feasibility, discusses the strengths and possible weaknesses of the proposed scheme and illustrates its energy efficient operation. |

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.
