Ad hoc wireless networks convey messages between transmitters, or nodes, without the need for any central control. However, the current situation forces emergency workers to keep to recommended guidelines for constructing such a wireless network, which dictates laying each node at a distance of 15 or 30 meters and at crucial points, like the corners of buildings. These nodes cyclically report back to a command centre to ensure that the nodes are still in contact.
Utilizing off-the-shelf hardware, the team built two prototype networks. One uses a Crossbow MICA2 Motes, which transmits radio signals at 900 megahertz, and the other, using Linux-based Gumstix transmitters, a Wi-Fi network that operates at 2.4 gigahertz. The speciality of this algorithm is that it should be able to work with any wireless hardware and on any available spectrum and has the potential to improve considerably emergency force readiness.
