For five years (2006-2011), Plug and Play Process Control (P3C) was one of the largest projects in our section at Aalborg University. Now, it is time to wrap up another work package of P3C (probably the last one), defined around the wireless communication framework of Plug and Play (PnP) control systems.
The main results will be presented in two distinct areas: 1) Signal propagation in underground and confined areas, and 2) Access and Networking protocols that can accommodate the required ser-vices for PnP control systems. The former finds application in only one of the P3C case studies where nodes are placed underground. After reviewing all potentially useful methods for signal propagation, Magnetic Induction (MI) is chosen as the winning candidate. New findings are docu-mented in antenna design of magneto-inductive communication systems. They are verified by sim-ulations and lab-scale experiments.
For the latter part, after reviewing Access and Routing protocols in industrial wireless networks, a deterministic Medium Access Control (MAC) protocol and a clustered flooding-based routing is recommended for wireless PnP control systems. Node clustering (network topology) is directly linked to the control system structure (let say control topology) via a control-derived routing metric. Functionality of the new routing metric is verified by simulations in a flooding-based routing algo-rithm.
