| Abstract | In wireless sensor networks, storage policy of sensed event affects the number of required control messages. If the number of control message can be reduced, the network lifetime can be increased because transmitting unnecessary control message requires extra energy consumption. In this paper, a local storage method with small control overhead is proposed for object tracking application in wireless sensor network. The main idea is to store the detected events in local storage and maintain the relation of the sensed data through a low cost implicit linked list among sensor nodes. When an object moves across the sensing field, detecting sensor can construct a linked list automatically along moving path of the object. The stored event records can be extracted by tracing the linked list from head to tail to get the complete information. When the memory space in a sensor node is full, a link reconstruction mechanism is proposed to distribute the heavy loads of sensor nodes to nearby nodes. Finally, performance analysis and simulation have been conducted to verify that the proposed method can reduce the amount of control messages and increase the network lifetime |

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.
