The packet scheduling problem has been deeply studied for lot of years by researchers in the computer science and telecommunications fields as an important solution that decides the order in which packets are sent over a link in order to provide QoS on a network. Recently, the packet scheduling has become again a challenging topic due to the massive use of wireless technologies (e.g. WiFi, LTE, 4G/5G), both for public and PPDR networks, with which to provide high QoS guarantees is still an open problem. Unfortunately, it is difficult to compare different solutions and actually test them in order to select the most proper packet scheduler for each particular environment.
