| Abstract | With routing paths being modified after each sink movement, delivering data to a mobile sink in a wireless sensor network (WSN) can be a challenging issue. Updating the sink location with messages to maintain a route frequently could result in great energy consumption in the sensors. Moreover, the number of message collisions is proportional to the control overhead of the sink location update. This paper develops a RIpple Sink Exploration scheme, or RISE, to efficiently guide the data to the mobile sink. The source which generates the raw data explores the sink location with no knowledge of node locations. The design proposed in this paper allows for updating sink locations without any bottleneck affects. Simulation results show that the RISE scheme saves more energy than previous designs, achieving greater network longevity. Also, RISE can be applied to a multiple-sink scenario with a small updating cost. |

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.
