In this paper, additional emphasis has been placed on developing decentralized data processing methodology for Wireless Smart Senor Network (WSSN). An output-only modal identification algorithm is modified for implementation in a distributed array of processors embedded within a network of wireless smart sensor prototypes. Using a 30 meters long railway overpass bridge as a testbed, an experimental verification of the decentralized data processing is presented. In order to compare the identification precision of different network topologies, acceleration responses were obtained under centralized and 3 different decentralized topologies.
