Performing an Experimental Platform to Optimize Data Multiplexing

This article is based on preliminary work on the OSI model management layers to optimized industrial wired data transfer on low data rate wireless technology. Our previous contribution deal with the development of a demonstrator providing CAN bus transfer frames (1Mbps) on a low rate wireless channel provided by Zigbee technology. In order to be compatible with all the other industrial protocols, we describe in this paper our contribution to design an innovative Wireless Device (WD) and a software tool, which will aim to determine the best architecture (hardware/software) and wireless technology to be used taking in account of the wired protocol requirements. To validate the proper functioning of this WD, we will develop an experimental platform to test different strategies provided by our software tool. We can consequently prove which is the best configuration (hardware/software) compared to the others by the inclusion (inputs) of the required parameters of the wired protocol (load, binary rate, acknowledge timeout) and the analysis of the WD architecture characteristics proposed (outputs) as the delay introduced by system, buffer size needed, CPU speed, power consumption, meeting the input requirement. It will be important to know whether gain comes from a hardware strategy with hardware accelerator e.g or a software strategy with a more performing scheduler. At the end, our experimental platform will be a tool for characterizing different WD.
