Outage Analysis for Drone Assisted Multi-user Coded Cooperation

UAV-Assisted Network Coded Cooperation by Using Height-Dependency Shaping Parameters in Nakagami-m Faded Channel

“…However, in a UAVassisted network, the channel gain changes with the UAV height, while in [9] the authors considered only two extreme fading channels for modelling the A2G links. The closedform expression of an outage probability [28] for the UA-NCC system is also derived by using Rayleigh as a smallscale fading and a fixed path-loss exponent for large-scale fading. The relaying scheme used at UAV is AF and SC is used at destination nodes for the purpose of analysis.…”

“…The relaying scheme used at UAV is AF and SC is used at destination nodes for the purpose of analysis. However, in [28], the height-dependent parameters is not considered for modelling small-scale as well as large-scale fading, which further affects the true performance of the network. Simulation-based outage analysis [29] is performed using AF at the UAV and MRC at the destination node in a probabilistic channel model.…”

“…First UA-NCC was proposed in [8] to improve the diversity and throughput of the system over disaster/post-catastrophe scenarios. The authors analyzed performance of UA-NCC [9], [10] over an air-to-ground (A2G) channel model based on Rayleigh fading, Rician fading and the probability of occurrence of a line-of-sight (LoS) model. However, the probability-based channel model considered two extreme cases for modelling A2G links, i.e., Rayleigh or Rician fading, whereas in practice, these A2G links take any general fading distribution that lies between the Rayleigh and Rician channel models depending on the UAV height.…”

“…To the best of our knowledge, few literatures consider both uplink and downlink along with NC at UAV for the multiuser scenario [8]- [10]. The authors developed the framework for the UA-NCC system using Rayleigh, Rician, and combination of both (Rayleigh and Rician) channel distribution for A2G links for analysis purposes.…”

“…The existing literature [8]- [10] has also not tackled the analytical framework for the UA-NCC system while incorporating a height-dependent shaping parameter for modeling the Nakagami-m fading channel. The one solution for incorporating all the channel variation gain is Nakagamim fading.…”
