Throughput maximization under guaranteed dissemination coverage for VANET systems

摘要: Vehicular Ad Hoc Network (VANET) technology enables efficient inter-vehicular communications for the broad-casting of public-safety and other critical message flows among unmanned autonomous vehicles. A key challenge in VANET broadcasting is to achieve a high throughput rate while at same time assure delivery packet all vehicles traveling over targeted segment highway. We have proposed Backbone (VBN) protocol dynamically synthesizing networking scheme that supports from Road Side Unit (RSU) along Though proven significant throughput-rate improvements compared with existing protocols, design VBN maximizes end-to-end guaranteeing coverage scope has not been addressed. In this paper, we develop an analytical model accurately characterizes maximum performance achievable under prescribed outage probability constraint. consider spatial-reuse TDMA-based VBN. joint optimization inter-relay distances, transmission rates, factors, which yet addressed literatures, carried out. These results are confirmed by comparison simulation results. They also serve as essential benchmark upper bounds characterize behavior robust distributed applicable systems provide vehicle-to-vehicle stochastically roaming highway
