This paper consider a Drone Assisted Network Coded Cooperation (DA-NCC) scenario for Line of Sight (LoS) channel environments. For analysing the performance of DA-NCC, Decode-and-Forward (DF) protocol is used at the drone and Selection Combining (SC) is performed at the destination node. An analytical closed-form formulation of the outage probability is devised and proven through simulations to assess network performance of the DA-NCC system. In order to have a better understanding of deterministic networks, a discussion on capacity and a comparison of alternative rectangular designs for deterministic networks are also presented. Insightful results on the relation among drone height, DNC-noise and network geometry may play an important role during the performance analysis of the DA-NCC system. Using closed-form expressions of performance measures, system designers can quickly examine the effects of various parameters on the DA-NCC network’s performance.
