We extend the probabilistic key-based approach for wireless sensor networks concerning the slow rekeying and path key reestablishment processes. By introducing a novel, energy efficient, distributed, and faster scheme, we attempt to replace the existing ordinary rekeying method of probabilistic key management scheme through a deterministic algorithm that works on both the base station and on each...
This paper introduces a sensor network testbed, X-sensor, that integrates multiple sensor networks deployed at different sites. X-sensor provides three functionalities: (a) a sensor network search which enables users to find a sensor networks appropriate for experiment and data acquisition, (b) a sensor data archive which provides users with various sensor data acquired by sensor nodes, and (c) an...
