An Efficient Transition Algorithm For Seamless Drone Multicasting
Many drone-related applications (e.g., drone-aided video capture, drone
traffic and safety management) require group communications between drones to
efficiently disseminate data or reliably deliver critical information, making
use of the line-of-sight coverage of drones to realise services that ground
devices may not be capable of. This paper studies highperformance yet
resource-efficient mobile drone multicasting via trajectory adjustment. We
first analyse the trajectory adjustment condition to determine whether a
straight-line trajectory is fully covered by the multicast or not, by
conducting simple computation tasks and with controlled overhead traffic. We
then propose the trajectory adjustment scheme to provide a new trajectory with
controlled travel distances. The ETTA algorithm is finally presented to apply
the trajectory adjustment condition and scheme to a drone transiting between
forwarders whose coverage do not overlap. The algorithm relies on multicasting
forwarders, instead of additional transition forwarders, to fully cover the
adjusted trajectory, helping to control interference and network traffic load.
Our NS2 simulation results demonstrate that ETTA, as compared to other mobile
multicasts, can achieve guaranteed performance for drone receivers in a
multicast with heavier traffic loads.Comment: 6 pages, 7 figure
