Energy Efficient Method For Communication Between A Wireless Sensor Network And An Industrial Control System

摘要

A method for communication between a wireless device node in a wireless sensor network and control apparatus or control processes of an industrial control system. The wireless network includes a plurality of device nodes and at least one gateway. The method includes receiving at a gateway an aggregated data packet or a final address in the ICS. The gateway processes the data packet, detects that it is an aggregated data packet and reconstructs the original data packets contained therein. The gateway then sends each of the original data packets as standard data packets to the intended final address in the ICS. In other aspects of the invention a method, system and a computer program for carrying out the method are described.
