  Current drone delivery systems mostly focus on point-to-point package
delivery. We present a multi-stop drone service system to deliver packages
anywhere anytime within a specified geographic area. We define a skyway network
which takes into account flying regulations, including restricted areas and
no-fly zones. The skyway nodes typically represent building rooftops which may
act as both recharging stations and delivery destinations. A heuristic-based A*
algorithm is used to compute an optimal path from source to destination taking
into account a number of constraints, including delivery time, availability of
recharging stations, etc. We deploy our drone delivery system in an indoor
testbed environment using a 3D model of Sydney CBD. We describe a graphical
user interface to monitor the real-time package delivery in the skyway network.
