Communication networks play a fundamental role in the response to massive catastrophes. In case of emergency, the main purpose of public authorities is to avoid damages for people and for buildings and the presence of a reliable communication infrastructure is vital. In this context, the use of IEEE 802.15.4 Wireless Personal Area Networks seems particularly appropriate to allow communications among security agents and for data collection, thanks to their characteristics of self-configurability, flexibility and low cost. In this paper the authors present a centralized algorithm that selects the best node to perform the PAN coordination in accordance to rules related to the concept of network depth and they extend the proposal with a distributed heuristic in order to have it working in an autonomic way.
