Following the success of the inaugural SeNAmI workshop in Dunedin, New Zealand in 2008, and the second SeNAmI workshop in Hiroshima, Japan, in 2009, this event once again aims to bring together researchers from academia and industry to present and discuss recent trends and advances in sensor networks and ambient intelligence, and from such engagement foster innovations towards technology maturity of sensor-based AmI systems and applications.Topics of interest include but are not limited to: * Cognitive wireless sensor networks * Sensor networking with context and ambient awareness * Nature or bio-inspired designs for ambient sensing and intelligence * Cross-layer design and optimization of sensor-based AmI systems * Reasoning and inference for sensor/RFID-based systems * Multi-modal sensor fusion for smart environments * Cyber-physical systems for human-centric applications * Ambient energy harvesting and energy-efficiency issues for sensor networks * Sensor or sensor-embedded object localization and target tracking * Cooperative in-network sensor information processing * Intelligent and mobile agents for embedded ubiquitous computing * Sensor networking in heterogeneous environments * Privacy, security, and trust management * AmI architectures, platforms, applications, and services * Prototypes, testbeds, and real-world deployments(source: iliad.aut.ac.nz)
