This paper proposes drone assisted device‐to‐device cooperative communication (DA‐DDCC) for critical situations during post‐disaster management. The proposed network utilizes the autonomous mode of D2D communication for setting up the link in the absence of a central node. This network incorporates cooperative communication using drone in D2D session for improving reliability of the overall system. A probability‐based statistical channel model for such networks is proposed by taking the statistical independence of links into consideration. Unlike the existing air‐to‐ground (A2G) channel models that use either Rayleigh or Rician distribution for uplink (UL) and downlink (DL) channel modelling, our approach takes the probability of occurrence of line of sight (LoS) into account while predicting the appropriate channel distribution for UL and DL separately. For performance evaluation of the proposed …
