Propagation modelling and performance assessment of aerial platforms deployed during emergencies

摘要

This paper proposes a channel model for aerial platforms deployed for disaster relief that aims to optimize the underlying ad hoc network performance. Channel modelling has been motivated by existing empirical and ATG propagation models and their resilience and scalability for aerial platforms. Grade of Service (GoS) is the benchmark used to set the desired performance of a trunked system. Thus, two GoS concepts are being considered: probabilities of blocking (Erlang B), and delay (Erlang C). The Received Signal Strength (RSS) performance of rescue teams is then simulated. Our prediction results show that aerial platforms offer much promise in providing robust communication links during emergency relief operations.
