The ability to geometrically represent sensed phenomena within a wireless sensor network can provide a more concise view than enumeration of all nodes identifying a phenomenon. A more concise view of sensed data can reduce the communication and energy costs of data analysis and extend the lifetime of the network. We propose a distributed edge detection technique that identifies connected perimeters for sensed phenomena within wireless sensor networks. The technique operates in arbitrarily

We implemented our technique and conducted extensive experiments; results show that our technique provides accurate perimeters for all sensed phenomena within a wireless sensor network even in the presence of irregularly shaped phenomena.
