Double-Cross-Correlation Processing for Blind Sampling-Rate and Time-Offset Estimation
IEEE/ACM Transactions on Audio Speech and Language Processing, 2021Coherent processing of signals captured by a wireless acoustic sensor network (WASN) requires an estimation of unknown parameters such as the sampling-rate and sampling-time offset (SRO and STO) of asynchronous sensor clocks.

Security in wireless actor & sensor networks (WASN): towards a hierarchical re-keying design
International Conference on Information Technology: Coding and Computing (ITCC'05) - Volume II, 2005 Our work aims to address the challenging security issues in an important information infrastructure - large-scale and low-energy wireless actuator and sensor networks (WASN). Since WASNs have specific network constraints and data transmission requirements compared to general ad hoc networks and other wireless/wired networks, the security issues need to
