DATA AGGREGATION METHOD AND NETWORK ARCHITECTURE FOR ROBUST REAL-TIME WIRELESS INDUSTRIAL COMMUNICATION

摘要

A wireless data network includes a master wireless node and a plurality of slave wireless nodes that are configured to transmit data using at least two independent channels. A first slave wireless node transmits data to a second slave wireless node using a first independent channel concurrently to a third slave wireless node transmitting data to the master wireless node using a second independent channel during a first time slot, the transmission from the third slave wireless node including a fixed overhead time. The second slave wireless node transmits the data from the first slave wireless node and additional data for the second slave wireless node to the master wireless node during a second time slot, the transmission from the second node including the fixed overhead time.
