    Motion tracking and data aggregation in distributed sensor networks using mobile agents
    (2005) Shivakumar, S.; Vinaykumar, K.
    In this paper a distributed, energy aware and collaborative approach for motion tracking and data aggregation in distributed sensor networks is proposed based on mobile agents. Proposed approach is simulated using network simulator (NS2) and the results are compared with that of the client-server model approach based on energy consumed for tracking and data aggregation. Results show that mobile agent based performs very much better than that of client server approach.

    Semantic image retrieval system based on object relationships
    (2013) Shivakumar, S.; Goel, N.; Ananthanarayana, V.S.; Cyriac, C.; Rajaram, P.
    Semantic-based image retrieval has recently become popular as an avenue to improve retrieval accuracy. The 'semantic gap' between the visual features and the high-level semantic features could be narrowed down by utilizing this kind of retrieval method. However, most of the current methods of semantic-based image retrieval utilize visual semantic features and do not consider spatial relationships. We build a system for content-based image retrieval from image collections on the web and tackle the challenges of distinguishing between images that contain similar objects, in order to capture the semantic meaning of a search query. In order to do so, we utilize a combination of segmentation into objects as well as the relationships of these objects with each other. © 2013 IEEE.
