摘要：This paper proposes a reliable system to overcome the weakness of current the HF radio communication system for oceanic aeronautical flight routes. This system uses only one aeronautical VHF channel with air-toair radio relay system based on local mobile Ad-hoc networks. For access to/from all aircrafts in the system, a TDMA (Time Division Multiple Access) scheme is proposed to be used where each aircraft is assigned one time slot during its presence in the system in order to transmit its own packet by itself or relay them using neighbouring aircrafts. These packets contain aircraft position, ID, relative direction which are used to build a routing table at each aircraft. In addition, several algorithms for relaying packets; schemes to reduce the packet-loss-ratio as well as to reduce the interference caused by surrounding aircrafts have been proposed. The simulations have shown the improvement of such proposals when examining system performance under real air-traffic scenarios. This system strengthens the reliability of oceanic aeronautical communication and increases situational awareness of all oceanic flights as an effective solution to operate more flights on the ocean but in higher safety.
