Abstract:
A self-organizing, scalable, heterogeneous and location aware WSN architecture called Disaster Aid Network (DAN) for assisting the responders to provide efficient emergency response was proposed in our previous work. The two main aspects of DAN are the communication and localization aspect. As part of the DAN communication aspect, in this paper we have undergone empirical investigations to identify the suitability of ZigBee’s 2.4 GHz operation for DAN. A new self-configuring mechanism for patient data access by the doctor at the disaster site is also proposed. As part of the DAN localization aspect, in this paper we have implemented two new Bayesian filter based algorithms called Improved Range-Based Monte Carlo Patient Localization and Range- Based Unscented Kalman Filter Patient Localization for real time localization of large number of patients at the disaster site. The close-to-reality simulations of both these algorithms is done using a disaster management mobility model to identify their suitability for patient tracking. The new localization solution in tandem with the emergency response system shall facilitate efficient logistic support at the disaster site.
