Micro base station aided vehicular ad hoc networking

摘要: We consider a heterogeneous network system in which micro base station nodes receive critical message flows from their associated wireless cellular backbone infrastructure and multicast them directly to vehicles that travel close vicinity. To assure delivery of these messages all other traveling along the highway, we make use vehicular ad hoc (VANET) provide for vehicle-to-vehicle transport messages. For this purpose, it is essential design achieves high throughput rate while assuring packet ratio minimal in-transit queueing delays. propose VANET networking scheme identified as (VBN) through are located properly selected nominal positions linear highway segment elected serve relay nodes. employ flow admission control mechanism at source, regulating pace transmission admitted packets. Closed form analytical expressions derived approximate computation system's end-to-end capacity rate. Through simulation analyses, confirm precision calculations. show ability CSMA/CA access schemes well emulate operations when managed by spatial-reuse TDMA schemes. In designing network, allocate resources assign parameters manner equalizes rates incurred across components hybrid system.
