Improving ISO 11783 file transfers into mobile farm equipments using on-the-fly data compression

摘要

It is considered the bandwidth bottleneck problem arising in ISO 11783 networks of mobile farm equipments when large file transfers are performed. To overcome this problem, a compression protocol called ISOBUSComp allowing the implementation of dynamic ("on the fly") data compression services for general ISO11783 file transfers is proposed. As a result, transmitting Electronic Control Units are free to choose any data compression technique they wish and receiving Electronic Control Units need not to be aware of such decisions, but just be able to process a suitable Universal Decompression Virtual Machine. Comprehensive simulation studies show that dynamic data compression services built upon the proposed protocol help to reduce bus utilization of ISO 11783 networks between a 28% and a 63%, thus speeding up the time for large file transfers.
