We consider decentralized control of a process with multiple sensors, controllers and actuators interconnected by analog erasure links. To stabilize the process, feedback information has to be transmitted over both implicit signaling channels through the process and over external erasure channels. However, the signaling is complicated by the fact that in the absence of guaranteed acknowledgments, the transmitter cannot be certain that the receiver has received the intended data. Based on a data flow network model, a necessary condition for the mean squared stabilizability is obtained. Stabilizing algorithms are then designed to prove the sufficiency of the condition.
