Content-aware transmission in UAV-assisted multicast communication
Content-aware transmission in UAV-assisted multicast communication
To alleviate the explosive growth of data trafficcaused by the increased use of smart devices, new transmissiontechniques are needed to increase the utilization of limitedbandwidth resources and for providing high transmission ratesin future wireless networks. On the other hand, due to theirflexibility and autonomy, unmanned aerial vehicles (UAVs) areconsidered as a potential candidate to support ubiquitous connectivity and operate as flying base stations, where the deploymentof UAVs can affect the quality of experience (QoE) of users.Hence, in this paper, we employ UAVs as aerial base stationsto transmit data to ground users (GUs) via air to ground (A2G)communication links, where we show how content awareness canhelp improve the data rate. Specifically, we design two contentsharing(CS) data transmission schemes to improve the averagedata rate of the GUs. Additionally, two UAV deployment strategies,namely the fixed-point deployment scheme and traversesearchdeployment scheme, are proposed based on the proposedCS transmission schemes. The simulation results demonstratethat our proposed data transmission schemes combined withtheir proposed deployment schemes outperform the traditionaltransmission scheme by 26 bits/s/Hz and 51 bits/s/Hz, respectively.

Abstract
To alleviate the explosive growth of data trafficcaused by the increased use of smart devices, new transmissiontechniques are needed to increase the utilization of limitedbandwidth resources and for providing high transmission ratesin future wireless networks. On the other hand, due to theirflexibility and autonomy, unmanned aerial vehicles (UAVs) areconsidered as a potential candidate to support ubiquitous connectivity and operate as flying base stations, where the deploymentof UAVs can affect the quality of experience (QoE) of users.Hence, in this paper, we employ UAVs as aerial base stationsto transmit data to ground users (GUs) via air to ground (A2G)communication links, where we show how content awareness canhelp improve the data rate. Specifically, we design two contentsharing(CS) data transmission schemes to improve the averagedata rate of the GUs. Additionally, two UAV deployment strategies,namely the fixed-point deployment scheme and traversesearchdeployment scheme, are proposed based on the proposedCS transmission schemes. The simulation results demonstratethat our proposed data transmission schemes combined withtheir proposed deployment schemes outperform the traditionaltransmission scheme by 26 bits/s/Hz and 51 bits/s/Hz, respectively.
