In this paper, an industrial Wireless Local Area Network (iWLAN) solution to control industrial robots (iRBs)
in large-scale factory automation (FA) environment is addressed. In the large-scale industrial network composed of multiple
access points (APs), a delay time during roaming from one AP to another AP causes a discontinuation of the control of
the iRBs. This roaming delay is usually induced by two processes; 1) scanning for a new access point and 2) authenti-
cation at the new access point. In order to avoid roaming delay, we propose a novel access scheme using pre-registration
and time-synchronization. In this scheme, all APs operate in same channel with time-synchronization, and each iRBs are
pre-registered to every AP before control. The analysis results show that the proposed scheme realizes zero delay, zero
communication cost and low storage requirements for roaming. |
