Abstract:
This paper investigates a problem that is usually studied in communication theory, namely routing in wireless networks, but it offers a control oriented solution -- particularly for decentralized control systems -- by introducing a new routing metric. Routing algorithms in wireless networks have a strong impact on the performance of networked control systems which are built upon them, by imposing latency, jitter, and packet drop out. Here, we have gone one step further from only investigating the effect of such communication constraints, and have directly intervened in the design of the routing algorithm for control systems in order to: 1) realize our preferred network topology and data traffic pattern, and 2) making it feasible to add and remove sensors, actuators, and controllers without having to decommission and/or re-design the system. Moreover, the end-to-end latency and jitter in our system tend to be minimal as a result of robustness of the algorithm to topology modifications. The proposed routing solution combines traditional flooding-based routing scheme with a novel method of clustering nodes based on correlation analysis between existing and emergent sensors and actuators of a control system.
