| Abstract | Geographic routing has been considered as an energy efficient and simple routing protocol for wireless sensor networks. It utilizes only geographical location information without global network structures to route data packets. To take these advantages of geographic routing, a source node should be aware of the location of a sink node. Methods that the source node efficiently obtains the sink location information, however, have been scantily studied yet. In this paper, we propose a restricted linear flooding scheme to obtain sink location in wireless sensor networks. The source node sends location query message and the sink node sends location announcement message to specified direction respectively. The node located on a crossing point of these two message forwarding paths informs the source node about the sink location information. Then the source node sends data to the sink node by geographic routing. The proposed scheme also constructs a virtual restricted linear flooding zone inside the network to guarantee the existence of the crossing point. Simulation results show that proposed scheme is more efficient in terms of energy consumption than existing protocols. |

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.
