An optimized OPC UA transport profile to bringing Bluetooth Low Energy Device into IP networks

摘要

Because energy efficiency is gaining more importance these days and Bluetooth Low Energy (BLE) could be used to make use of potential everyday objects into Internet of Things (IOT) — a software, platform and vendor independent common service interface that can be used in such low resource devices has high potential. OPC UA is an emerging middleware solution that addresses the above points but is bulky due to its abundant features. Further optimization is necessary to bring the OPC UA into such resource-limited devices. We have scaled down the OPC UA protocol stack footprint down to the chip level [16]. In this paper, we propose an optimization approach to minimize the OPC UA network footprint.
