The objective of my PhD thesis is to build robust data models in distributed sensing environments using adaptive resource management techniques. Cyber Physical Systems are distributed systems-of-systems that perform reliable data acquisition in order to build efficient data models. Data models are mathematical expressions that describe the attributes of the observed environments. These models can be used for monitoring, tracking and predicting the dynamics of the physical phenomena. Also, data models aid in formulating decision-making procedures under resource constraints.

The objective was to build a sound localization system on a wireless sensor network using reconfigurable architectures. This included building a reconfigurable analog frontend and customizing an existing Sound Localization algorithm for implemenation on a Programmable System-on-Chip (PSoC) microcontroller. A wireless Star-network was then built using PSoC1 nodes as the Sampling nodes and PSoC3 as the processing node. Dynamic reconfiguration was performed to improve the accuracy and efficiency of the localization algorithm.
