what is bubble sensing

Bubble-Sensing, a new sensor network abstraction that allows mobile phones users to create a binding between tasks (e.g., take a photo, or sample audio every hour indefinitely) and the physical world at locations of interest, that remains active for a duration set by the user. We envision mobile phones being able to affix task bubbles at places of interest and then receive sensed data as it becomes available in a delay-tolerant fashion, in essence, creating a living documentary of places of interest in the physical world. The system relies on other mobile phones that opportunistically pass through bubble-sensing locations to acquire tasks and do the sensing on behalf of the initiator, and deliver the data to the bubblesensing server for retrieval by the user that initiated the task
