Evaluation of Age Control Protocol (ACP) and ACP+ on ESP32
share
Age Control Protocol (ACP) and its enhanced version, ACP+, are recently proposed transport layer protocols to control Age of Information of data flows. This study presents an experimental evaluation of ACP and ACP+ on the ESP32 microcontroller, a currently popular IoT device. We identify several issues related to the implementation of these protocols on this platform and in general on short-haul, low-delay connections. We propose solutions to overcome these issues in the form of simple modifications to ACP+, and compare the performance of the resulting modified ACP+ with that of the original protocols on a small-delay local wireless IoT connection.
