Current Projects

  • To facilitate advanced research in wireless sensor network technology, we are currently in the process of deploying a wireless sensor network testbed at Washington University in St. Louis.

  • Wireless sensor networks have traditionally been used as specialized single-application platforms. However, with the emergence of integrated sensing systems such as automatic building management, wireless sensor networks are evolving into shared, multi-application infrastructure. This paradigm shift raises the need for a framework for deploying multiple applications on a wireless sensor network such that application QoS requirements are met while also optimizing the use of the limited sensor network resources.

Recent Projects

  • 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 need to deal with the dynamics introduced by the mobility of users, physical objects, and sensor nodes. This project established a spatiotemporal communication framework for wireless sensor networks through a field of study that integrates real-time systems and mobile computing research.
