A 3-D Deployment and Coverage Algorithm for Aircraft Cargo

Cargo environment safety plays an important role in civil aviation. It is a huge threat if an emergency event happens, for example, a fire breaks out on a plane. An accurate alarm of fires can help the crew tackle with it in time and avoid larger property loss. However, there exists false fire alarms during a flight which usually leads to unexpected landing. Using Wireless Sensor Network (WSN) for fire monitoring can remarkably decrease false alarms. This paper proposes a WSN deployment and coverage strategy in aircraft cargo so that every place is under at least one sensor’s monitor to avoid ignoring any possible fire source in order to help improve the accuracy of fire alarm. The simulation results demonstrate that our algorithm can successfully deploy a WSN with 100% coverage rate, which is usually called k-coverage when k = 1.
