  Abstract

In this paper, we propose DTDMA(dynamic time division multiple access) protocol adapting a concept of time mirroring(TM), called TM-TDMA. Airborne relay network serves relay communication using UAV(Unmanned Aerial Vehicle). However, adapting the current TDMA to airborne relay networks, the delay in the relay process increases because the traffic is concentrated in the relay terminal. The TM-TDMA combines two consecutive timeslots called mirroring slot as downlink immediately after uplink. Slot assignment in the TM-TDMA is achieved by deviding an empty mirroring slot with multiple mini-slots and the node sends the request packet and confirms by itself. Additionally, seamless voice communication is possible by using the proposed voice guarantee algorithm. Simulation results show that the TM-TDMA eliminates delay in relay transmission and guarantees seamless voice communications.
