The goal of this research is to develop autonomous networks of sensors that perceive their environment and respond to it, anticipating information needs by the network and by users of the network, repositioning and organizing themselves to best acquire and deliver the information.

Mobile sensor networks are sensor networks in which nodes can move under their own control or under the control of the environment. Mobile networked systems combine the most advanced concepts in perception, communication, and control to create computational systems capable of interacting in meaningful ways with the physical environment, thus extending the individual capabilities of each network component and network user to encompass a much wider area and range of data. A key difference between a mobile sensor network and a static sensor network is how information is distributed over the network. Under static nodes, a new task or data can be flooded across the network in a very predictable way. Under mobility this kind of flooding is more complex. Under natural mobility this depends on the mobility model of the nodes in the system.

We are studying issues related to the deployment, localization, self-organization, maintenance, and in-network data processing in such networks.

We are working with a range of applications and devices. We use Mica Motes and MIT Crickets for ground applications. We use our in-house sensor node called Aquafleck for underwater applications.
