Wireless sensor networks have been widely used in scientific research, industrial manufacturing, and environmental monitoring over the past decade. Using pre-existing networks to assist in responding to disaster events can be cost-effective. In this paper, we present Alert, a software framework for retasking wireless sensor networks, enabling these networks to respond rapidly to unexpected events without neglecting their originally assigned tasks. Alert, built upon Deluge [1], is a wireless
