(a) Connectivity graph of the camera nodes from the previous figure. Marked links correspond to the camera network graph

(b) Camera network graph—adjacent links between the cameras indicate that cameras have overlapped FoVs. The dotted lines correspond to the case when the cameras have overlapped views, but cannot communicate directly. The communication schedule must provide message forwarding between these cameras
