TCP and UDP Fairness in Vehicular Ad Hoc Networks
In this paper, a new MAC based approach has been proposed to improve fairness in TCP and UDP flows in VANET. Since TCP has been developed for wired networks, in wireless networks, especially the ones based on IEEE 802.11 standard, it has fairness problems. The common proposed MAC based approaches, using a timer, have only worked on fairness improvement among TCP flows. UDP flows form major parts of network traffics. According to the lack of flow and congestion control mechanisms in UDP traffics, in the authors' proposed approach, both types of traffic have been considered together.
