Sensor networks are promising unprecedented levels of access to information about the physical world, in real time. Many areas of human activity are starting to see the benefits of utilizing sensor networks, in almost all such cases, sensor networks are statically deployed. The next evolutionary step for sensor networks is to handle mobility in all its forms. This panel aims to identify the benefits from such a step and recognize the resulting research challenges.
