Boundary Detection for Sensor Networks
Wireless sensor networks have a variety of applications, such as environment monitoring, structural monitoring, remote exploration, condition-based maintenance, commercial surveillance, and national asset protection. These applications require the network to monitor a certain type of non-local spatiotemporal phenomenon, collaboratively process gathered information, and respond to external events or report results. There are different types of phenomenon that can be observed by a network of sensors. For some phenomena such as fire, gas leak, chemical attack and biological attack, it is critical to track the boundary of the affected area.
