Abstract

This paper presents a comparative analysis, set in Vanet scenarios and based on simulations, between the well-known IEEE 802.11p standard and an efficient slotted protocol based on RR-Aloha (MS-Aloha). Notably the chosen slotted protocol is completely distributed and based on reservation, and has been specifically designed to face issues typical of mobility, while preserving quality of service guarantee. The simulations are carried out using the same settings for CSMA/CA and MS-Aloha: separate analyses are meant to discuss the specific characteristics of each of them while a common final discussion is aimed at highlighting the weaknesses and points of strength of the proposed MAC protocols.
