Abstract

In this paper, we focus on two fundamental aspects in the design of Bus-based Vehicular Networks: the building of bus mobility scenarios for validating solutions and the dissemination of messages on the network. We present a methodology for generating bus mobility scenarios based on official data and simulation tools. In this regard, we consider the city's road map and additional traffic infrastructure elements. In addition, traffic demand for different days of the week is generated based on GTFS data provided by the city's transport agency. We validate our scenarios with official data, and through a comparative analysis, we show the relevance of this work compared to existing alternatives in the literature. We present a novel routing protocol named BR3C, which aims to forward messages between bus lines for data dissemination. BR3C (Bus Routing protocol based on Community and Centrality Characteristics) considers social metrics extracted from the contacts between bus lines for decision-making. As a result, our protocol significantly reduces delivery latency while keeping delivery ratio values similar to state-of-the-art. (AU)
