In this paper, we develop a wireless relay network model for an unmanned aircraft (UA) system, where an UA serves as a resilient moving relay among the ground stations with disconnected communication links in the event of disasters. A fixed-wing type is considered as our UA model, since it can operate longer than a rotary-wing UA without recharging battery, but the former can fly only in a circular...
Wireless networks formed by peer devices or device-to-device communications are drawing more and more attention recently. In IEEE 802 Standardization Committee, TG15.8 was set up to develop a new standard for peer aware communication (PAC). PAC is expected to provide fast neighbor discovery, offload traffic for infrastructure-based networks, provide emergency links without fixed central control, etc...
This paper presents a measurement setup for transport protocol of wireless relay network using a unmanned aircraft (UA). The UA can fly back and forth to ferry data from multiple ground based access points or ground stations (GSs) that are located in the distance without connection to the backbone due to the network disconnection caused by a large-scale disaster. In such disaster area, a demand of...
This paper analyzes the bit error probability for the proposed relaying protocol that applies a network coding to a communication system with a small unmanned aircraft (UA) in order to achieve diversity gain. We consider the scenario where the UA circles around above the fixed area automatically and it relays the signals between the two ground access points (GAPs) separately located with long distance...
