Virtual Networks and Software Router Approach for Wireless Emergency Networks Design
Under the circumstances of a disaster, public telecommunication networks are usually not trustworthy enough for rescue services. These infrastructures become frequently overloaded or damaged and turn out to be unusable. For this reason, nowadays the typical approaches for communication in catastrophe aid support are mainly based on reserved Professional Mobile Radio (PMR) infrastructures like APCO or TETRA. The European TETRA, an ETSI standard adopted in more than hundred countries worldwide, is principally designed for speech and short messaging among first aid operators (fire fighters, policemen, etc.), and offers complementary low-rate data transmission (e.g. 3-14 kbps).
