Wireless sensor networks have the potential to revolutionize the way humans interact with physical environments through a broad range of applications including highway traffic coordination, security surveillance, etc. Future sensor-based applications will have to meet new kinds of spatiotemporal specifications under severe resource limitations. Required data freshness guarantees will impose strict timing constraints over the delivery of data from the environment to the end user, both in terms of end-to-end deadlines and sampling rates. Data aggregation will be driven by the locality of environmental events and will entail coordination activities subject to spatial constraints. The communication delay associated with a multi-hop transmission across a sensor network is affected by the spatial distribution of both data flows and sensors. At the same time, sensor networks will need to deal with the dynamics introduced by the mobility of users, physical objects, and sensor nodes. This research aims to establish a spatiotemporal communication framework for wireless sensor networks through a field of study that integrates real-time systems and mobile computing research. We are developing new communication protocols that are optimized for sensor networks by incorporating timing and space properties in scheduling and routing algorithms. Another key element of this project is developing a rigorous spatiotemporal analysis that draws upon theories on real-time schedulable utilization bound and network geometry. The analysis will provides a methodology for designing dependable sensor networks able to support mission critical applications in which performance predictability is a paramount concern.
