The emerging field of wireless sensor networks (WSNs) offers new computation and communication platforms that enable novel, low cost, high volume applications. Significant efforts have been made in recent years in building large-scale wireless sensor networks (WSNs) from small devices with integrated sensing, computation, and wireless communication capabilities. There are exciting opportunities and challenges in developing system support that optimally manages the tremendous hardware resources in WSNs. In one project, we are developing an innovative system called Mosaic (Multi-level Optimization of System resource Allocation In Cooperative organizations). Taking a modular multi-level approach, Mosaic provides unprecedented capabilities in optimizing the usage of the underlying dynamic and uncertain hardware resources and providing user-friendly interfaces and resource-aware abstractions and services that facilitate the concurrent execution of multiple applications on heterogeneous WSNs. We have also developed various methods for node localization, position estimation, topology control, data-centric routing, and streaming data processing.
