Abstract: Data acquired by numerous wireless sensors in a large industrial setting is communicated to the operations center via nodes in defined geographic cells where the signals from the sensors may be depowered to naturally attenuate below the perception of most other receiving nodes in the industrial system. It would be optimal that signals would attenuate sufficiently such that most signals in a cell are not discernible to receiving nodes in adjacent cells, but some sensors near the boundary of a cell will probably have to be set at sufficient power that the nearest adjacent receiving cell would necessarily perceive the signal. Data rejection protocols would exclude data from outside a cell and the advantage of the invention is that it minimizes the volume of errant signals leading to more reliable and robust data for operators.

Abstract: Aspects of the present disclosure provide techniques for enabling data traffic having security of different Purdue Enterprise Reference Architecture security levels to traverse a common network. Techniques disclosed herein maintain logical separation between the different data traffic types by assigning each to a discrete virtual LAN, and discretely encrypting each data traffic type.
