Recently, a few applications appeared that emulate the behaviour of a wireless ad-hoc network at the application layer, or make it accessible through a full programming framework on the Android platform. We show in this demo how to enable mesh networking at the network level, in a transparent manner to applications. We use this network to relay information regarding physiological monitoring of a team of fire-fighters in a fire scenario. The application developed in Android receives the information from a wearable sensor and transmits it to a controller that visualizes the current team progress.
