Both severity and frequency of disasters in highlydense industries such as ready-made garment factories have increased to an alarming level in recent times. Technological advancement addresses a number of aspects of post-disaster rescue missions for such events, however, facilitating the missions through providing real-time information about the survivors to the first responders is yet to be focused in the literature. Absence of such real-time information may create a gap between the survivors' requirements and the first responders' action. To bridge the gap, in this paper, we propose a novel system (named Sign of Life) exploiting wireless sensor networks for escalating the post-disaster rescue missions. Even though we mainly focus on ready-made garments factories in the paper, it can be utilized in other similar cases. Here, we propose a network architecture for the system and develop a prototype required for implementing the system. We present ns-2 simulation results pertinent to our proposed network architecture. Finally, we point out how we plan to enhance our proposed system in future.
