Sensor data management technologies for infrastructure asset management

Abstract: This chapter discusses selected data management issues that are commonly shared by structural health monitoring (SHM) systems. First, data processing and management issues at the wireless sensor node are discussed, with special attention on reducing energy consumption inherent to wireless data communication. Second, issues such as communication constraints, protocol design and dynamic code migration, that are related to in-network data and software management are discussed. Third, persistent data storage and remote data access schemes, including a multi-agent-based framework for data processing and sensor self-monitoring, are presented. Technologies will continue to evolve to address these issues and to support data-rich SHM systems.
