Abstract
A method includes providing wireless service to a mobile leaf node using at least one first infrastructure node in an industrial control or monitoring system. The method also includes detecting movement of the mobile leaf node away from the at least one first infrastructure node. The method further includes handing off the mobile leaf node to at least one second infrastructure node in the industrial control or monitoring system so that the at least one second infrastructure node provides the wireless service to the mobile leaf node. The wireless service provided to the mobile leaf node remains deterministic. Various techniques can be used to detect the movement of the mobile leaf node. Also, the first and second infrastructure nodes could be in different clusters of nodes, and various techniques can be used to support handoffs between infrastructure nodes in different clusters.
