Drone communications make use of line-of-sight coverage of drones to realise services that ground devices may not support. Many relevant applications such as video capture by drones and drone traffic management, require group communications between drones to efficiently disseminate data. In this paper, we study high-performance yet resource-efficient multicasting between drones that may change their locations in order to fulfill their missions. This is achieved by proposing novel trajectories

The presented efficient transition via trajectory adjustment (ETTA) algorithm is developed based on our analysis of the condition that determines when a straight-line trajectory between the origin and destination of a drone is not seamless. The algorithm then proposes the trajectory adjustment schemes that form a new interference-controlled and travel-distance-controlled trajectory to replace an interrupted straight-line trajectory. Our NS2 simulation results demonstrate that ETTA, as compared to other mobile multicasts, can achieve guaranteed performance in a multicast with heavier traffic loads.
