In an industrial environment, a manufacturing plant is composed of, among other things, sensors, actuators, and controllers that form control loops. Such elements are often referred to as a programmable logic controller (PLC). Techniques are presented herein that allow manufacturing plants to achieve decreased latency and increased reliability by placing the PLCs in a sensor-controller-actuator system closer to each other while minimizing the deployment cost to the extent possible. This is achieved by deploying PLCs as moving containers in an access point (AP) for, as an example, wireless manufacturing plants. Aspects of the presented techniques dynamically deploy PLC applications and roam them in locations such that the number of hops between a sensor’s output, the control logic (e.g., a PLC), and an actuator’s input may be kept at a minimum to achieve the lowest latency and jitter and the maximum reliability. Further aspects of the presented techniques leverage elements of the Internet Engineering Task Force (IETF) Reliable and Available Wireless (RAW) initiative, a Path Computation Element (PCE), a Path Selection Engine (PSE), etc.
